17Now I urge you, brothers, to look out for those who cause divisions and offenses, contrary to the doctrine which you learned, and turn away from them.
18For such people do not serve our Lord Jesus Christ, but their own belly, and through smooth speech and flattering, they deceive the hearts of the innocent.
19For your obedience has become known to all. Therefore I rejoice on your behalf; but I want you to be wise in what is good, and innocent to what is evil.
20And the God of peace will crush Satan under your feet quickly. The grace of our Lord Jesus Christ be with you.
