Romans 16:17-23 reminds believers to guard against divisive people and false teachers. This sermon calls the church to be watchful, confront offenses biblically, and avoid those who distort sound doctrine—whether through legalism, flattery, or smooth talk. Division is compared to fire and gangrene, devastating congregations when left unchecked. Practical steps include addressing conflict directly, speaking well of others, and refusing to give a platform to falsehood. The message ends with Paul’s encouragement that God will soon crush Satan under the church’s feet, urging believers to preserve unity through the Spirit’s power.
