Romans 16:17-20 NKJV
Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned, and avoid them. For those who are such do not serve our Lord Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple. For your obedience has become known to all. Therefore I am glad on your behalf; but I want you to be wise in what is good, and simple concerning evil. And the God of peace will crush Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen.
