What does Paul mean by "mark them which cause divisions" in this passage?

When Paul says "mark them which cause divisions and offences," he is telling the believers to pay careful attention to people who stir up conflict in the church or teach things that go against the gospel they had already been taught. To “mark” them is to notice and identify them, not shrug it off or ignore it. These people mix truth with new ideas that do not match the message about Christ. Paul’s aim is to protect the church’s unity in the truth, not to silence every disagreement, but to guard against those who pull people away from the true doctrine.

Why does Paul command believers to avoid those who cause divisions and teach error?

Paul tells the believers not only to notice divisive teachers but also to avoid them. These people do not really serve the Lord Jesus, even if they speak about him. Instead, they serve their own “belly,” meaning their own desires and gain. By staying close to such teachers, believers can easily be drawn in by smooth words and flattery. Avoiding them protects the church from confusion, damaged relationships, and a twisted view of the gospel. Paul sees this as an act of care for the church’s spiritual health and for the honor of Christ’s name.

Why does Paul praise the Romans’ obedience yet still warn them about deception?

Paul says that the Romans’ obedience is known everywhere, and he rejoices over them. They are teachable and ready to follow the gospel. But this same openness can make them targets. Someone who is eager to obey can sometimes accept teaching too quickly without testing it. So Paul adds a loving warning. He wants them to stay obedient, but also to grow in wisdom so that they do not stumble through naivety. His warning does not mean he distrusts them. It shows his care, knowing that even a faithful church can be harmed if it is not watchful.

What does it mean to be "wise unto that which is good, and simple concerning evil"?

To be “wise unto that which is good” means to grow in understanding of what is true, right, and pleasing to God. It includes knowing the gospel well, learning to discern sound teaching, and seeing through tricks that would pull us away from Christ. To be “simple concerning evil” means to be innocent and harmless when it comes to sin and deceit, not clever in doing wrong or planning harm. Paul is not praising ignorance of God’s word. He wants believers to have sharp judgment about good, while remaining unskilled and inexperienced in evil ways.

What does "the God of peace shall bruise Satan under your feet shortly" teach about spiritual victory?

This promise shows that God, who brings peace, will also defeat the great enemy behind all lies and division, Satan. The picture of bruising or crushing under their feet echoes the first promise that the serpent would be crushed. Satan has already been judged through Christ, but he still fights against God’s people. Paul tells the believers that God will soon make Satan’s efforts fail and give the church victory, not only at the final judgment but also in their present struggles. Their hope is not in their own strength, but in the God of peace who acts for them.

How is God both the "God of peace" and the one who crushes Satan in this passage?

Calling God the “God of peace” might sound strange right beside a promise to crush Satan, but the two belong together. God brings true peace by dealing with the source of unrest and deception. Satan works through lies, division, and sin, which disturb both the church and individual hearts. When God defeats Satan’s work, he restores and protects peace among his people. So God’s peace is not weak or passive. It is strong enough to overthrow evil. Paul wants the believers to know that their fight against false teaching and sin is carried forward by the God who gives peace.

Why does Paul end this warning with "The grace of our Lord Jesus Christ be with you"?

After speaking about dangerous teachers and the fight against Satan, Paul ends with a simple blessing: “The grace of our Lord Jesus Christ be with you.” This shows that the strength to discern, to avoid false teaching, to stay obedient, and to stand firm in the battle does not come from us. It comes from the grace of Christ. His undeserved kindness, help, and presence are what keep believers safe and steady. Paul’s warning is serious, but he does not leave them looking only at themselves. He points them back to Christ’s ongoing grace as their sure help.

Romans 16:17

Q: How do "good words and fair speeches" deceive the hearts of the simple?

Paul says that false teachers use “good words and fair speeches” to deceive “the hearts of the simple.” Their talk sounds kind, wise, and spiritual, but it is empty and self-serving. They promise much, but their promises do not match the true message about Christ. Those who are “simple” here are not wicked, but they are not careful or discerning. Because they trust too quickly and do not test what they hear, they are easily misled. Paul is warning that pleasant tone and impressive words are not proof that a message is from God.

KJV

Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.

Avoid Divisions

Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.

For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.

For your obedience is come abroad unto all men. I am glad therefore on your behalf: but yet I would have you wise unto that which is good, and simple concerning evil.

And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen.
