17Now I exhort you, brothers, to watch out for those who cause divisions and offenses, contrary to the doctrine you have learned, and avoid them.
18Because such people do not serve our Lord Jesus Christ, but their own belly, and by smooth talk and flattery they deceive the hearts of the unsuspecting.
19I rejoice over you because your obedience has become known to all, but I want you to be wise as to what is good, yet innocent as to what is evil.
20The God of peace will quickly crush Satan under your feet! The grace of our Lord Jesus Christ be with you.
