Introduction
When I first decided to preach from Romans 16:17–19, the title “Guard the Gospel and Walk in Obedience” came to my mind. The passage is a clear warning from Paul to the church in Rome: watch out for those who create divisions and obstacles contrary to the doctrine you have learned. The language is direct, the instruction specific.
But as soon as the title formed in my mind, another question surfaced:
How do the three priorities of the church affect these two things — guarding the gospel and walking in obedience?
I remembered what Jack Miller taught about the three priorities of the church, which I described in my doctoral work:
- Go with the gospel.
- Disciple Christians to go with the gospel.
- Defend the faith as you go with the gospel.
This framework matters because “guarding the gospel” can easily be misunderstood. If we think of guarding as our first priority, it can become static — a defensive stance, concerned mostly with holding our ground. But if we place it where Jack placed it — as the third priority of the church, in the context of going and discipling — then guarding becomes part of an active movement. It’s protecting the message while carrying it forward.
Once that connection was in place in my mind, the rest of the passage began to take shape around it. Romans 16:17–19 would let us see both what guarding the gospel looks like in its proper place and what happens when that priority is reversed. This led to a second major theme: walking in obedience.
Here again, the context matters. Paul’s call to “obedience of faith” (Romans 1:5; 16:26) is not obedience to the law as a means of earning God’s favor. It is the obedience that comes from trusting Christ — the response of faith to God’s command to believe in His Son (Acts 17:30; John 3:36). This obedience is the doorway into a life that truly fulfills the law, because it unites us to Christ, the One who has fulfilled the law for us (Romans 7:1–6; Galatians 5:6).
By the end of my work on this week’s sermon, I had two clear goals I wanted listeners to be clear about:
—First, what “the three priorities of the church” are and how “guarding the gospel” fits into them.
—Second, what Paul means by the “obedience of faith” and how it relates to “obedience to the law.”
These same two aims give shape to this essay. The structure of the text and the title work together: when guarding the gospel is in its right place, it clarifies what walking in obedience looks like. When the priorities are reversed, it distorts both.
1. The Three Priorities of the Church
When Jack Miller described the work of the church, he did so in terms of priorities. These were not meant to be abstract ministry theory. They were a practical ordering of what the church must do if it is going to be fruitful and faithful to Christ. Jack came to these priorities through observation, reflection on Scripture, and experience in ministry. He had seen and pastored churches busy with many activities but unclear on how those activities related to the mission Christ had given.
Jack’s order of the three priorities of the church:
- Go with the gospel.
- Disciple Christians to go with the gospel.
- Defend the faith as you go with the gospel.
Each one builds on the previous. If the first priority is neglected, the others lose their meaning and power. If the second is skipped, the work will be thin and unsustainable. And if the third is moved to the front, the whole posture of the church changes.
The first priority — going with the gospel — is drawn from Jesus’ Great Commission (Matt. 28:18–20) and His promise in Acts 1:8 that the Spirit would empower His people to be witnesses “to the end of the earth.” Going is active, relational, and intentional. It is taking the good news of who Jesus is, what He has done, and why it matters into the real settings where people live. It is the first thing because without going, there is no mission.
The second priority — discipling Christians to go — ensures that the work of going is not left to a few. This is the “every member ministry” vision Paul describes in Ephesians 4:11–16: leaders equip the saints for the work of ministry so that the body builds itself up in love. Discipleship here means more than personal growth; it is growth with a purpose. Christians learn the gospel deeply, apply it to their own lives, and gain the skill to share it with others — in the church, at home, and beyond.
The third priority — defending the faith as you go — is necessary because the gospel will be challenged. False teaching, cultural pressures, personal fears, and spiritual opposition all work against it. But defending the gospel is meant to happen as we are going with the gospel. The church is not to build walls and hide; it is to guard the gospel while carrying it forward. The forward-facing shield in Ephesians 6 is a good picture: protection designed for an advancing army, not a retreating one.
Why this order matters becomes clear in practice:
—When going with the gospel is first, the church is outward-facing. Its energy flows toward people who need to hear and believe.
—When discipling to go is second, the church’s teaching and training are shaped by mission. The focus is on the fullness of the gospel and how to communicate it clearly and lovingly in real conversations.
—When defending as you go is third, guarding the gospel is active and purposeful — it protects the message so it can keep moving into new lives.
When the order is reversed, the results are very different. If defending the faith comes first, the church can take on a fortress mentality. It becomes reactive instead of proactive. Teaching drifts toward winning arguments or protecting identity rather than proclaiming Christ. Discipleship becomes about mastering defenses rather than knowing God and the One whom He has sent (John 17:3). “Going” becomes occasional or optional, because the focus has turned inward. The result is often division, distraction, and a loss of urgency for the mission.
This priority order also shapes the relationship between teaching (διδαχή) and learning (μανθάνω). When the first priority is going with the gospel, teaching centers on the gospel’s content — who Jesus is, what He has done, and why it matters — and how to bring that message into real settings. Learning means internalizing that message personally, preaching it to yourself, and practicing it with others until it becomes a natural part of your life. In this order, teaching and learning are dynamic and mission-driven.
In Romans 16:17–19, Paul’s call to “watch out” fits naturally within this framework. Guarding the gospel is essential, but it is most effective when done in motion, in the context of going and discipling. This is how the church remains both faithful to the truth and fruitful in the mission Christ has given.
2. What We Mean by the Gospel
Before we go further into Paul’s instructions, I want to set out plainly what I mean when I use the word “gospel.”
In recent months, I’ve made it my habit in nearly every essay or sermon to pause and define what I mean by the gospel clearly. Some may wonder why I repeat this so often. The answer is simple: I need to hear it again myself, and I want to be sure that when I say “gospel,” I am not speaking vaguely. If the gospel is the power of God for salvation (Romans 1:16), then it needs to be clear in my own mind and in the minds of those who hear me.
For that reason, I have often returned to Jack Miller’s A New Life booklet. In it, Jack distilled the gospel into what he called the “Five Facts.” I’ve come to see these as a concise and faithful way to keep the heart of the gospel in front of me. They are not the only way to summarize the gospel, but they are rooted in Scripture and keep the message both clear and personal.
Here they are:
1. Why did Jesus say He came into the world?
A loving God sent His Son Jesus into the world so that we may have a new and abundant life.
— John 10:10; John 7:37–38
2. Why are so many people without this new life?
Because we are self-centered and God is not at the center of our lives.
— Romans 3:10–12, 23
3. What separates us from God?
A bad record, a bad heart, and a bad master.
— Romans 6:23; Jeremiah 17:9; John 8:34
4. What is the greatest gift of the Father’s love?
Jesus, the God-man, suffered all the torments of hell as a substitute for His people. He was legally condemned by God as their representative, removing the barriers of a bad record, a bad heart, and a bad master. Risen from the dead, He now lives to give us a new record, a new heart, Himself as our Master, and the free gift of eternal life now.
— John 3:16; Galatians 3:13; 2 Corinthians 5:21; Romans 6:23; John 17:3; 1 Peter 1:3–5
5. How do we receive this new and abundant life?
By turning in sorrow from our sin and believing on the Lord Jesus Christ. And how do we continue in this new life? In the same way we began — “As you received Christ Jesus the Lord, so walk in Him.”
— Acts 3:19; Acts 16:31; Colossians 2:6
This gospel is both an announcement and a summons. It is God’s declaration of what He has done in Christ and His call to us to respond in faith. Everything Paul says in Romans — including his warnings in chapter 16 — flows from this message. When he speaks of “the doctrine you have been taught” (Romans 16:17), he is talking about this gospel in its fullness.
Keeping this definition in view matters for the rest of this essay. It keeps our focus on the right message, the right Person, and the right mission. Without it, the words “guard the gospel” risk becoming a slogan without substance. With it, we know exactly what we are guarding, and why.
Section 3 – Guarding the Gospel in Its Proper Place
Guarding the gospel is one of Paul’s central concerns in Romans 16:17–19. But in the framework of Jack Miller’s three priorities of the church, guarding is not the first priority—it’s the third. It only finds its proper shape and power when it follows going with the gospel and discipling Christians to go with the gospel. When guarding is placed first, it risks becoming defensive, suspicious, and static. When it is placed third, it becomes a forward-facing protection, keeping the message clear and uncorrupted while it is being carried into conversations, relationships, and communities.
This order matters because it changes our position, posture, and purpose. In a defensive-first model, guarding tends toward isolation—keeping perceived threats out rather than keeping the mission moving forward. In the go–disciple–guard model, vigilance is exercised on the move. The aim is not to keep the church safe by limiting exposure, but to guard the gospel as we engages one another and the world with its message.
That’s the framework Paul’s language supports in Romans 16:17–19.
3.1 Guarding the Gospel in Romans 16:17
Paul’s opening command in Romans 16:17 is clear:
“I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them.”
3.1.1 The verb “watch out” — σκοπέω
The Greek verb σκοπέω means to “look at closely, observe attentively, keep your eye on.” It is used in Philippians 3:17 to tell believers to “keep your eyes on” those who live according to the example Paul gave, and in Hebrews 12:15 to “see to it” that no one fails to obtain the grace of God.
The idea is not casual observation but active, intentional watchfulness—the kind a shepherd exercises over his flock or a sentry keeps at his post.
—Classical Greek: σκοπέω was used in military contexts for watching the enemy’s movements, and in philosophy for close examination of an idea or argument.
—Septuagint (LXX): Similar words appear in watchman imagery like Ezekiel 33:7, where the prophet is appointed as a “watchman” for Israel—a role that combines vigilance with the responsibility to warn.
—New Testament: It can be used positively (watch those who set a godly example) or negatively (watch out for threats to the church’s health).
In Romans 16:17, the posture of σκοπέω is active but not fleshly. It is not suspicion for its own sake, nor control over others, but careful discernment aimed at protecting the advance of the gospel.
When we link σκοπέω with the first of Jack’s three priorities (“go with the gospel”), we see that this watchfulness is meant to happen on mission. It is the vigilance of someone who is already moving with the gospel and is alert to threats that could distort the message or divide the team.
3.1.2 The threat: διχοστασίαι and σκάνδαλα
Paul names two dangers: “divisions” (διχοστασίαι) and “obstacles” (σκάνδαλα).
—Διχοστασία is a compound of δίχα (“apart”) and στάσις (“standing”), literally “standing apart.” It refers to separations, dissensions, or factionalism. In Galatians 5:20, it appears in the list of works of the flesh. In the LXX, it’s rare, but similar terms describe rebellion in Israel’s history.
—Σκάνδαλον is a “stumbling block” or “snare.” In Romans 9:33, Paul uses it for Christ Himself—the God-given stumbling stone. In Romans 16:17, however, σκάνδαλα are “contrary to the doctrine” the church had learned. These are man-made barriers: rules, tests, or expectations that obscure Christ and burden consciences.
Paul’s warning here is that both of these—divisions and false stumbling blocks—are contrary to “the doctrine” (τὴν διδαχήν) the believers had learned.
3.1.3 Doctrine learned: διδαχή and μανθάνω
The “doctrine” (διδαχή) is the teaching of the gospel itself, unfolded across Romans 1–15. It is not just abstract theology but the truth about Jesus—His life, death, resurrection, reign, and return—and what that means for life in Christ.
The verb “learned” (ἐμάθετε, from μανθάνω) means to gain knowledge through instruction and experience. In the NT, μανθάνω is used for discipleship—learning the way of Christ in both word and deed (cf. Matthew 11:29, “learn from me”).
This combination shows that Paul is talking about teaching and learning in a relational, experiential way. The doctrine is not just to be stored in the mind; it is learned in the life of the church as the gospel is believed, taught, shared, and lived out.
3.1.4 Avoid them: ἐκκλίνω
Paul adds the command to “avoid them” (ἐκκλίνετε). This verb means to turn aside, to keep away from. In the LXX, it is used for turning away from evil (Psalm 34:14; Proverbs 3:7). In the NT, it appears in 1 Peter 3:11—“let him turn away from evil and do good.”
The avoidance Paul commands is not passive indifference but an intentional stepping aside from those who persist in distorting the gospel or dividing the body. It is the refusal to give influence to someone who is working against the mission.
3.1.5 Guarding in Christ
Every one of these actions—watching, teaching, learning, avoiding—can be done either in the flesh or in Christ.
—In the flesh: watchfulness becomes suspicion; teaching centers on winning arguments; learning is about mastering defenses; avoidance is about personal comfort.
—In Christ: watchfulness depends on God’s wisdom in prayer; teaching centers on the gospel’s fullness and clarity; learning is relational and experiential; avoidance protects unity for the sake of gospel advance.
This is where the third priority of the church (defending the faith) finds its proper place. When it follows going and discipling, guarding the gospel becomes a forward-facing defense that preserves the clarity of the message while it is being shared—both with those outside the church and those within it who need the gospel daily.
3.2 Guarding Shapes Teaching and Learning
When guarding is practiced in its proper place, it sharpens the church’s teaching and energizes its learning. Teaching is anchored in the gospel’s content—who Jesus is, what He has done, and why it matters—and directed toward equipping believers to bring that message into their relationships. Learning becomes participatory: preaching the gospel to oneself, speaking it to one another, and living it out in the settings where God has placed us.
Guarding in this sense does not shrink the scope of teaching to a set of defensive arguments. Instead, it expands teaching into a dynamic engagement with the gospel in the real world. It ensures that learning is not just cognitive but relational and missional.
3.3 Guarding as Protection of Gospel Advance
Finally, guarding the gospel in its proper place serves the mission directly. It removes distortions that would slow or sideline the message. It preserves unity so that the church’s witness remains credible. It keeps the focus on Christ, the one true stumbling block God has placed before the world, and clears away the false stumbling blocks we might be tempted to add.
When guarding works this way—following going and discipling—it is not about keeping the church safe from the world; it is about keeping the gospel free to run (2 Thess. 3:1) in the world.
Section 4 – Division Weakens Gospel Advance
Paul’s warning in Romans 16:17–18 is not an abstract concern about theological disagreements. It is a direct pastoral instruction about a live threat: division and false stumbling blocks that work against the gospel’s advance.
When the church reverses the three priorities Jack Miller identified—putting defending the faith first, discipling second, and going last—this threat grows stronger. Defending becomes the focus, discipleship becomes about defending positions, and going becomes optional. The energy of the church turns inward, toward protecting itself or winning arguments, instead of outward, toward making Christ known. In that climate, divisions multiply, false obstacles appear, and the mission slows or stops.
4.1 Divisions and Obstacles in Romans 16:17–18
Consider again the two vivid terms used by Paul to describe the threat and scandal of false stumbling blocks
—Διχοστασία (divisions) — A compound of δίχα (“apart”) and στάσις (“standing”), literally “standing apart.” In the NT, it occurs in Galatians 5:20 in the list of “works of the flesh,” describing factions that fracture unity. In the LXX, related terms describe rebellion in Israel’s history, where leaders stirred up dissent for their own gain (e.g., Numbers 16, Korah’s rebellion).
—Σκάνδαλον (obstacles/stumbling blocks) — In its literal sense, it referred to a trap or snare. Paul uses it in Romans 9:33 for Christ Himself—the God-given stumbling stone that confronts unbelief. But here in Romans 16:17, these are not God-given. They are “contrary to the doctrine” the church has learned—human-made barriers that obscure Christ.
False stumbling blocks can take many forms:
• Added rules or traditions that become tests of belonging.
• Cultural or political litmus tests.
• Moral performance standards that replace grace.
When the church “puts anything in front of people before Christ”—whether moral performance, political alignment, or cultural conformity—it replaces the God-given stumbling block with its own. That burdens consciences, distorts the gospel, and discourages both those who do not yet believe and those in the church who need the gospel daily.
4.2 The Source and Strategy Behind the Threat
Paul explains in verse 18 that those causing these problems “do not serve our Lord Christ, but their own appetites” (κοιλία, literally “belly,” a metaphor for self-interest). They use “smooth talk” (χρηστολογία) and “flattery” (εὐλογία) to deceive the hearts of the naïve.
—Κοιλία — While it can refer to the physical stomach, it is often used metaphorically in Scripture for bodily desires or self-serving appetites (Phil. 3:19).
—Χρηστολογία — A rare word meaning “plausible-sounding speech” or “polished words” that make falsehood sound reasonable.
—Εὐλογία — In its positive sense, “blessing” or “good words,” but here it is empty flattery—language that wins trust while hiding true motives.
This combination—self-interest, persuasive speech, and deceptive flattery—is a well-worn strategy. In the garden, the serpent appealed to desire (“you will be like God”) and used smooth words to mask a lie. In the OT, false prophets often told the people what they wanted to hear (Jeremiah 6:14).
Paul’s concern is that such voices work inside the church, not just outside. If the church is not actively going with the gospel, it becomes more susceptible to these internal disruptions. Without the outward pull of mission, the inward pull of self-interest and factionalism fills the vacuum.
4.3 How Reversed Priorities Feed Division
Jack Miller’s order—(1) go with the gospel, (2) disciple Christians to go, (3) defend as you go—keeps the mission outward.
Reversing the order has predictable effects:
- Defending first shifts the focus to “protecting” before proclaiming.
- Discipling second becomes training in argument rather than training in gospel clarity and grace.
- Going last means it happens rarely, if at all.
Without active mission, differences inside the church loom larger. Every disagreement has more space to grow into division. Theological precision is still important, but without the context of mission, it can become a tool for control or exclusion rather than a means of clarity for gospel advance.
This is exactly the climate in which διχοστασία thrives. And once factionalism sets in, σκάνδαλα—the false stumbling blocks—are right there to trip over. The message becomes cluttered, and those both inside and outside the church encounter barriers to Christ that God never placed there.
4.4 The Impact on Teaching and Learning
In Romans 16:17, Paul warns against what is “contrary to the doctrine you have learned.” That phrase connects to the Greek διδαχή (teaching) and μανθάνω (learning).
—When priorities are right, teaching is centered on the gospel’s content—Christ crucified and risen—and its application in real life. Learning is relational, experiential, and aimed at living and sharing that message.
—When priorities are reversed, teaching can shift to defending a subculture or a set of preferences. Learning becomes about stockpiling answers to win debates, rather than growing in the grace and knowledge of Christ.
Paul warned Timothy about this in 1 Timothy 1:3–7: when teaching is driven by speculation rather than stewardship from God, it produces “vain discussion” instead of love from a pure heart, a good conscience, and sincere faith.
4.5 The Enemy’s Strategy
In the Old Testament, God sometimes granted victory to His people by causing confusion in enemy ranks (Judges 7:22; 2 Chron. 20:22–23). Paul’s warning here suggests that the enemy can turn this tactic against the church. If he can get an advancing gospel army to turn inward and fight itself, he doesn’t need to stop it directly. Division stalls the mission without a single external blow.
It is no accident then that Paul connects the divisions and creating stumbling blocks and obstacles to the presence of evil in Romans 16:19 and to Satan himself in Romans 16:20:
“For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil. The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus Christ be with you.”
That’s why guarding the gospel in the right order of priorities is so critical. It’s not just about internal harmony; it’s about maintaining the church’s readiness and ability to carry the message of Christ with clarity and love.
4.6 Summary of Section 4
When guarding the gospel is removed from its mission context, it easily becomes guarding ourselves. That reversal fosters division, multiplies false stumbling blocks, and re-centers teaching and learning on something other than Christ. The result is that the gospel’s advance is slowed, and the unity that should commend it to the world is fractured.
Guarding the gospel in its proper place, however, clears the path for the gospel to move forward—protecting its clarity, removing unnecessary barriers, and keeping the church’s energy aimed where it belongs: toward making Christ known among the nations and declaring the excellencies of His mercies that are new every day.
5. Christ Unites Us in the Obedience of Faith
Paul’s language about “obedience” in Romans has been carefully chosen and deliberately framed. He begins the letter by speaking of his apostolic mission “to bring about the obedience of faith” (Romans 1:5), and he ends the letter with the same phrase (Romans 16:26).
This “obedience of faith” is not obedience to the Mosaic law as a means of earning righteousness; it is obedience to the gospel itself — the royal summons of God to believe on His Son.
5.1 The Nature of “Obedience of Faith”
The Greek word Paul uses for “obedience” is ὑπακοή (from ὑπό, “under” + ἀκούω, “to hear”). It literally means “to hear under,” and it carries the idea of listening attentively with the intention to submit or respond. In Scripture, it is the kind of hearing that leads to action.
—Classical Greek: ὑπακοή was used for obeying commands or heeding instructions, often in military or household contexts.
—LXX (Septuagint): Used to translate Hebrew words for hearing and obeying God’s voice (e.g., Deut. 28:1–2).
—NT Usage: In Romans 1:5 and 16:26, it refers to the obedience that is faith — trusting submission to the gospel. In 2 Thessalonians 1:8, it describes those who “do not obey the gospel of our Lord Jesus,” placing unbelief in the category of disobedience.
The point is clear: in Paul’s mind, the gospel is not advice. It is not merely an offer to consider. It is a command from the living God to repent and believe (Acts 17:30; John 3:36). To refuse is to disobey; to believe is to obey.
5.2 The Gospel as a Royal Summons
Understanding the gospel as a summons reshapes how we think about obedience. In Eden, God’s command was clear: “You may surely eat of every tree… but of the tree of the knowledge of good and evil you shall not eat” (Gen. 2:16–17). Adam and Eve’s sin was not curiosity; it was rebellion against a clear command.
The gospel comes as a new covenant command: “Believe in the Lord Jesus, and you will be saved” (Acts 16:31). This is the “obedience of faith.” It is not obedience to the law in order to be accepted; it is the obedience that comes from trusting Christ for our acceptance.
Once we see this, the link between faith and obedience becomes unbreakable:
—Faith responds to God’s command to believe.
—That believing unites us to Christ.
—In that union, we are set free to live in ways that fulfill the law’s intent — love for God and neighbor.
5.3 Union with Christ and True Law-Keeping Love
Romans 7:1–6 is essential here. Paul uses the analogy of marriage: we were “married” to the law, bound to it as a covenant of works. But through the death of Christ, we have “died to the law through the body of Christ” so that we might “belong to another” — to Christ, who was raised from the dead — “in order that we may bear fruit for God.”
That shift in covenant relationship changes everything:
—The law is still holy, righteous, and good (Romans 7:12), but we no longer relate to it as a condemning husband.
—We now bear fruit for God out of our new union with Christ.
—This fruit is the fulfillment of the law’s righteous requirement (Romans 8:4) through “faith working out in love” (Galatians 5:6).
In other words, you cannot truly obey God’s law apart from obeying the gospel. Law-keeping love flows from gospel faith. Without that faith, attempts to obey the law either collapse into despair or inflate into pride.
5.4 Why This Matters for Guarding and Going
This is where Paul’s logic in Romans 16:17–19 connects to the obedience of faith. When the three priorities of the church are in their right order:
- We go with the gospel, calling people — believer and unbeliever alike — to trust and follow Christ.
- We disciple Christians to go, which means equipping them to live in the obedience of faith and to help others do the same.
- We defend the faith as we go, protecting the gospel’s clarity so that the obedience we are calling for is the obedience of faith, not obedience to man-made rules or cultural shibboleths.
When the priorities are reversed, obedience gets distorted. “Walking in obedience” gets redefined as conformity to the group’s distinctives or alignment with its cultural values, rather than faith in Christ expressed in love. The result is a church that may be busy, disciplined, and even zealous — but not actually producing the fruit of the gospel.
Guarding the gospel in going with the gospel is what keeps the gospel as the gospel. Paul’s “watch out” is not about pulling back; it’s about protecting the truth while advancing it. This is the heart of Jack Miller’s third priority — defend the faith as you go.
5.5 The Gospel’s Double Reach
One important point that emerges here — something I’ve emphasized often — is that going with the gospel is not just going to unbelievers. Paul was “eager to preach the gospel… to you who are in Rome” (Romans 1:15) — to believers. Every Christian needs the gospel daily, because the obedience of faith is not a one-time act at conversion.
We enter the Christian life by the obedience of faith, and we continue in it the same way:
“As you received Christ Jesus the Lord, so walk in him” (Colossians 2:6).
That means:
—We preach the gospel to ourselves.
—We share it with one another in the church.
—We take it to those around us who have not yet believed.
This daily rhythm keeps the obedience we practice tethered to the gospel we have received.
5.6 Summary of Section 5
The obedience of faith is God’s command to believe in His Son — a command that is also the gateway to a life of true law-keeping love. It begins with hearing and believing the gospel, and it continues as we live out that faith in union with Christ.
Guarding the gospel, in its proper place in the church’s priorities, protects the clarity of that call. It ensures that the obedience we pursue and teach is the obedience of faith — the only obedience that fulfills the law because it flows from Christ Himself.
6. Walking in Obedience Together
In Romans 16:19, Paul says:
“For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil.”
This is not a throwaway compliment. It ties directly to everything Paul has written about the obedience of faith from the beginning of the letter (1:5; 16:26) and connects to the practical way a church walks in obedience together.
Here, Paul joins affirmation with exhortation — rejoicing in their obedience while giving clear direction for how to continue in it.
6.1 Obedience in the Context of Community
Paul’s commendation — “your obedience is known to all” — is corporate. He’s not just talking about a few exemplary individuals; he’s referring to the collective life of the church in Rome.
This shows that obedience to Christ is not merely a private matter. The obedience of faith is expressed and sustained in the shared life of God’s people.
When a church walks in the obedience of faith together:
—Its unity commends the gospel to outsiders (John 13:34–35).
—Its members help each other persevere (Hebrews 3:12–14).
—Its collective life displays what the reign of Christ looks like in relationships, work, and worship (Ephesians 4:1–16).
The “together” is essential because the gospel we guard and carry is not an individual possession; it’s a shared stewardship (1 Timothy 6:20; 2 Timothy 1:14).
6.2 Wise About What Is Good
Paul’s first exhortation is to “be wise as to what is good.” Wisdom here is not abstract theory; it’s the skill in the art of Godly living that is in alignment with God’s will (cf. Proverbs 1:7; Colossians 1:9–10).
In the context of Romans 16, “what is good” is what promotes the gospel’s advance, strengthens the church’s unity, and reflects the character of Christ.
To be wise about what is good means:
—Knowing what builds up rather than tears down (Romans 14:19).
—Recognizing when an issue is worth contending for and when it is a matter of personal conscience (Romans 14:1–12).
—Having discernment about what will serve the mission and what will distract from it.
6.3 Innocent About What Is Evil
The second exhortation is to be “innocent as to what is evil.” This doesn’t mean naïve. Paul is not calling the Romans to ignorance about evil; he’s calling them to be untainted by it.
The word “innocent” (ἀκέραιος) conveys purity, simplicity, and integrity — being unmixed with evil. Jesus uses the same word in Matthew 10:16 when He tells His disciples to be “wise as serpents and innocent as doves.”
For the Romans, this meant resisting the divisive and deceptive tactics described in verses 17–18, behind which is Satan’s influence (verse 20).
For us, it means refusing to participate in or be shaped by behaviors, attitudes, or strategies that compromise the gospel — even if they seem effective in the moment.
6.4 Tying It Back to the Three Priorities
Walking in the obedience of faith together flows directly from the three priorities of the church in their right order:
- Go with the gospel — so that the obedience we walk in is always rooted in and propelled by faith in the gospel message itself.
- Disciple Christians to go with the gospel — so that every member is equipped to live and speak the gospel in their daily contexts.
- Defend the faith as you go — so that our guarding protects and promotes obedience of faith in the gospel, rather than replacing the gospel with rule-keeping or preference-guarding.
When the order is reversed, walking in the obedience of faith together is replaced with policing one another’s conformity to secondary matters. Unity fractures, mission stalls, and the gospel is overshadowed by internal disputes.
6.5 Obedience of Faith Producing Law-Keeping Love
As we saw in Romans 7:1–6 and Galatians 5:6, the obedience of faith produces the kind of love the law requires. This is how the law is fulfilled in the life of the church — not by striving to keep it in our own strength, but by walking in the Spirit, united to Christ.
Together, we bear fruit for God that reflects His character and advances His mission.
Walking in obedience together means:
—Encouraging one another in faith.
—Confronting sin in love.
—Forgiving as we’ve been forgiven.
—Pursuing what makes for peace and mutual upbuilding (Romans 14:19).
It’s a community project fueled by the gospel and empowered by the Spirit.
6.6 Romans 16:17–19 in This Light
Seen through the lens of the entire letter, the “obedience” Paul affirms in 16:19 is the obedience of faith. It is faith in the gospel he has proclaimed from the very first chapter.
Guarding the gospel from distortion is essential to preserving that obedience because faith rests on hearing the true message of Christ (Romans 10:17).
—In verse 17, Paul warns about those who cause divisions and create obstacles contrary to the gospel teaching the Romans had received.
—In verse 18, he exposes their motives: they serve their own appetites and use smooth talk to deceive the naive.
—In verse 19, he affirms the Romans’ obedience and urges them to remain wise about good and pure from evil.
6.7 Guarding and Walking — Inseparable
Paul’s words in Romans 16:17–19 show that both guarding the gospel and walking in obedience are inseparable.
—Guarding without walking leads to stagnation.
—Walking without guarding leaves the gospel vulnerable to distortion.
The health of the church depends on doing both, in the right order, and in the power of the Spirit.
When the three priorities are in order, guarding the gospel strengthens our going, and going keeps our guarding mission-focused.
The obedience we walk in is then the obedience of faith — a life lived in reliance on Christ, producing the love the law was always pointing to.
6.8 Summary of Section 6
Walking in obedience together is not simply about avoiding sin or doing good deeds. It is about living out the obedience of faith in community — guarding the gospel’s clarity, advancing its mission, and producing the fruit of love through our union with Christ.
This is why Paul rejoiced over the Romans’ obedience and why he urged them to be wise about what is good and innocent about what is evil. Their shared life in Christ was both the fruit of the gospel and the means by which the gospel would continue to spread.
7. Word Studies and Biblical-Theological Notes
Romans 16:17–19 contains a cluster of key terms that sharpen our understanding of Paul’s instructions.
These words are not abstract theological vocabulary — they are chosen for precision, rooted in the Scriptures, and rich with background meaning from the Old Testament, the Septuagint (LXX), the wider New Testament, and even classical Greek.
7.1 σκοπέω — “Watch out” (Romans 16:17)
Definition: to “look at closely, observe attentively, keep your eye on.”
—Classical Greek: Used in military contexts for watching enemy movements; in philosophy for close examination of an idea or argument.
—Septuagint (LXX): Similar watchman imagery, e.g., Ezekiel 33:7; the prophet appointed as a “watchman” for Israel, combining vigilance with the duty to warn.
—New Testament: Philippians 3:17 — “keep your eyes on” those who live according to the example; Hebrews 12:15 — “see to it” that no one fails to obtain the grace of God.
In Romans 16:17:
This is not casual observation but active, intentional watchfulness — the kind a shepherd keeps over his flock or a sentry maintains at his post. In Paul’s framework, this vigilance is exercised “on mission,” in line with Jack Miller’s first priority (“go with the gospel”) and second (“disciple Christians to go”).
7.2 διχοστασία — “Divisions” (Romans 16:17)
Definition: separation, dissension, factionalism. From δίχα (“apart”) + στάσις (“standing”).
—Classical Greek: Used for political or civic discord — parties standing apart.
—LXX: Rare, but similar terms describe rebellion in Israel’s history (e.g., Korah’s rebellion, Numbers 16).
—NT: Galatians 5:20 — listed among the works of the flesh, alongside enmity, strife, jealousy.
In Romans 16:17:
Paul warns against people whose teaching or influence leads believers to “stand apart” from one another in ways contrary to the gospel.
7.3 σκάνδαλον — “Obstacles / Stumbling Blocks” (Romans 16:17)
Definition: a trap, snare, or stumbling block.
—Classical Greek: Originally referred to the trigger of a trap — something that causes one to fall or be ensnared.
—LXX: Used for causes of sin or downfall (e.g., Leviticus 19:14, “do not put a stumbling block before the blind”).
—NT: Romans 9:33 and 1 Peter 2:8 — Christ Himself as the God-given “stumbling stone.” Here in Romans 16:17 — man-made obstacles “contrary to the doctrine” learned.
In Romans 16:17:
Paul distinguishes between the God-given stumbling block (Christ crucified) and false stumbling blocks — extra rules, cultural shibboleths, or human agendas that obscure Christ and burden consciences.
7.4 διδαχή — “Teaching / Doctrine” (Romans 16:17)
Definition: instruction, the content of what is taught.
—Classical Greek: General teaching or training.
—LXX: Often used for God’s instruction, particularly the Torah.
—NT: In Acts and the Epistles, διδαχή frequently refers to the apostolic teaching centered on Christ (Acts 2:42; 1 Timothy 4:13).
In Romans 16:17:
This is the gospel as Paul has expounded it throughout Romans — not abstract theory but the truth of Christ’s life, death, resurrection, reign, and return, with all its implications for life.
7.5 μανθάνω — “Learn” (Romans 16:17)
Definition: to gain knowledge through instruction and experience.
—Classical Greek: Learning through study or apprenticeship.
—LXX: Learning God’s ways, often tied to covenant obedience (Deut. 5:1).
—NT: Discipleship — learning in both word and deed (Matthew 11:29, “learn from me”).
In Romans 16:17:
Paul assumes the Romans’ “learning” has been experiential — the gospel taught and lived out in the community, not merely memorized.
7.6 ἐκκλίνω — “Avoid” (Romans 16:17)
Definition: to turn aside, keep away from.
—Classical Greek: To deviate from a course, physically or morally.
—LXX: Turning away from evil (Psalm 34:14; Proverbs 3:7).
—NT: 1 Peter 3:11 — “let him turn away from evil and do good.”
In Romans 16:17:
This is intentional avoidance — refusing to grant influence to those who persist in distorting the gospel or dividing the body.
7.7 κοιλία — “Appetite” (Romans 16:18)
Definition: literally “belly,” figuratively “desire” or “appetite.”
—Classical Greek: Physical stomach; also metaphor for greed or lust.
—LXX: Can refer to the seat of desire or inner being (Prov. 18:8).
—NT: Philippians 3:19 — “their god is their belly” (self-indulgence as idolatry).
In Romans 16:18:
Paul contrasts serving “our Lord Christ” with serving one’s own desires — a fundamental misalignment of allegiance.
7.8 χρηστολογία — “Smooth Talk” (Romans 16:18)
Definition: pleasant, flattering speech. From χρηστός (“kind, good”) + λόγος (“word”).
—Classical Greek: Language meant to please, sometimes with manipulative intent.
—LXX: The idea appears in Proverbs’ warnings against flattering speech (Prov. 5:3; 7:21).
—NT: Unique to Romans 16:18.
In Romans 16:18:
This is persuasive speech that sounds kind and wise but works against the gospel’s truth.
7.9 ὑπακοή — “Obedience” (Romans 16:19)
Definition: from ὑπό (“under”) + ἀκούω (“to hear”), meaning attentive hearing that leads to submission or action.
—Classical Greek: Obedience in military, household, or legal contexts.
—LXX: Obedience to God’s voice (Deut. 28:1–2).
—NT: Romans 1:5; 16:26 — “obedience of faith.” John 3:36 — belief and obedience intertwined.
In Romans 16:19:
Paul commends the Romans’ obedience — not mere rule-keeping, but the faith-filled response to the gospel.
Summary of Section 7:
Every key term in Romans 16:17–19 is bound to Paul’s overarching aim: a church guarding the gospel in the midst of mission, walking together in the obedience of faith, and resisting the distortions and divisions that would derail that mission.
8. Practical and Theological Implications
Romans 16:17–19 is not simply a closing warning in Paul’s letter.
It gathers up key threads from the whole book and lays them alongside practical realities in church life.
The three priorities of the church — going with the gospel, discipling Christians to go, defending the faith as we go — form a lens through which to read and apply Paul’s words.
These priorities affect how we guard the gospel, how we walk in obedience, and how we avoid distortions that come from reversing the order.
8.1 Guarding on Mission vs. Guarding in Isolation
When guarding is in its rightful place as the third priority, it happens in the context of going and discipling:
—The church is already moving with the gospel.
—Watchfulness protects that advance, keeping the message clear and the mission unhindered.
Guarding on mission looks like:
—Testing teaching by the gospel’s content (Acts 17:11).
—Removing man-made stumbling blocks so only Christ is the offense (Romans 9:33; 1 Peter 2:8).
—Protecting unity so love commends the message (John 13:34–35).
When guarding becomes the first priority, the posture shifts:
—Energy is spent on policing boundaries rather than advancing the gospel.
—Suspicion replaces discernment; people are viewed as threats first, neighbors second.
—The mission field shrinks to those already inside, and even there, divisions multiply.
The contrast is stark:
—Guarding on mission protects so the gospel can keep moving forward.
—Guarding in isolation protects a static position, often at the cost of gospel clarity and unity.
8.2 The Three Priorities and the Shape of Teaching and Learning
When the first priority is going with the gospel:
—Teaching (διδαχή) centers on the fullness of the gospel — who Jesus is, what He has done, why it matters.
—Learning (μανθάνω) means internalizing that message, preaching it to oneself, practicing it with others, and living it out in the real world.
When the second priority is discipling Christians to go:
—Teaching is mission-shaped — designed to equip every member to speak the gospel into daily life.
—Learning is apprenticeship — hearing, seeing, and practicing gospel ministry alongside others.
When the third priority is defending the faith as you go:
—Teaching trains believers to identify distortions without losing gospel focus.
—Learning includes developing discernment, rooted in Scripture and shaped by mission needs.
If the order is reversed:
—Teaching can drift toward argument-winning rather than disciple-making.
—Learning becomes about memorizing defenses instead of knowing Christ.
—The gospel becomes assumed rather than taught — replaced by secondary concerns.
8.3 The Obedience of Faith in Personal and Corporate Life
Personal implications:
—The obedience of faith begins with hearing and believing the gospel (Romans 10:17).
—It continues by living in reliance on Christ (Colossians 2:6), bearing fruit that fulfills the law’s intent (Romans 8:4; Galatians 5:6).
—Guarding the gospel in daily life means filtering influences, teachings, and habits through the lens of the gospel.
Corporate implications:
—The church’s unity becomes a visible witness to the gospel (John 17:20–23).
—Guarding together means cultivating a culture where the gospel is spoken often, applied graciously, and defended wisely.
—Walking together in the obedience of faith means encouraging one another in belief, confronting sin in love, and keeping the main thing the main thing.
8.4 Implications for Apologetics, Theology, and Discipleship
When priorities are in order:
—Apologetics serves the mission. Defending the faith is aimed at removing barriers to hearing the gospel, not winning debates for pride’s sake.
—Theology is lived and shared, not just stored in books — doctrine is for worship, mission, and love.
—Discipleship multiplies gospel carriers, not just guardians.
When priorities are reversed:
—Apologetics can become combative, alienating those we aim to reach.
—Theology can turn into a badge of identity rather than a foundation for worship and service.
—Discipleship can focus on conformity to group norms rather than transformation in Christ.
8.5 Guarding and the Enemy’s Strategy
Paul’s warning in Romans 16:17–20 echoes Old Testament accounts where God turned enemy armies against themselves (Judges 7:22; 2 Chronicles 20:22–23).
The enemy can twist this tactic against the church — using division to halt gospel advance without ever engaging directly.
—Inward conflict drains energy from outward mission.
—Secondary battles distract from the main fight — proclaiming Christ.
—Suspicion erodes love, making the church less credible to those watching.
Guarding in mission-responsible ways is spiritual warfare — resisting the enemy’s attempt to replace God’s stumbling block (Christ) with our own.
8.6 The Gospel’s Reach — Inside and Outside
Guarding and going are not separate spheres — the gospel’s reach is always both:
—To unbelievers, calling them to the obedience of faith.
—To believers, reminding them of the same gospel in which they stand (1 Corinthians 15:1–2).
Paul was eager to preach the gospel “to you who are in Rome” (Romans 1:15) — to the church.
This guards against gospel-presumption — the drift that happens when we think we’ve “moved on” from the gospel to more advanced topics.
Summary of Section 8:
Guarding the gospel is not an end in itself — it is part of a movement.
When the three priorities of the church are in their right order, guarding protects clarity, going advances mission, and discipling multiplies carriers of the message.
Reversing the order blurs the gospel, breeds division, and confuses obedience.
The health and mission of the church depend on keeping these priorities aligned — and living them together.
Conclusion —The Three Priorities of the Church: Guarding the Gospel and Walking in the Obedience of Faith
Guard the Gospel and Walk in Obedience — Paul’s words in Romans 16:17–19 bring those two realities together in a way that’s both urgent and practical.
We’ve seen that guarding the gospel has a specific place in the life of the church. Jack Miller’s three priorities give us the framework:
- Go with the gospel.
- Disciple Christians to go with the gospel.
- Defend the faith as you go.
Guarding is not a retreat into self-protection; it’s a forward-facing work that happens on mission. It’s the shield raised in the advance, not the wall we hide behind.
We’ve also seen that walking in obedience means living out “the obedience of faith” — God’s command to repent and believe the gospel, which unites us to Christ and by faith produces in us the law-keeping love the law has always required.
You cannot obey God’s law without first obeying the gospel. And you cannot guard the gospel well if your life, or your church, is not walking in that obedience of faith together.
Our first goal was that you would leave this essay knowing clearly what the three priorities of the church are, how guarding fits into them, and what happens when those priorities are reversed.
When the three priorities of the church are in order, guarding the gospel fuels gospel advance; when reversed, guarding fractures unity and distracts from the mission.
Our second goal was that you would leave this essay with the biblical apparatus to discern the difference between “the obedience of faith” and “obedience to the law.”
The obedience of faith is life in union with Christ, by the Spirit, producing the very love the law commands. It is the only way to truly keep the law in God’s sight.
So as we go with the gospel, the call is simple and profound: keep the mission moving.
Guard the message as you carry it.
Walk together in the obedience of faith, so that our life together commends the gospel we proclaim.
And trust the God who called you to finish what He started — in you, in this church, and in the advance of His kingdom.
