¹⁷Now I urge you, brothers, to watch out for those who create divisions and obstacles that are contrary to the teaching you have learned. Turn away from them. ¹⁸For such people are not serving our Lord Christ, but their own appetites. By smooth talk and flattery they deceive the hearts of the naive. ¹⁹Everyone has heard about your obedience, so I rejoice over you. But I want you to be wise about what is good and innocent about what is evil. ²⁰The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus Christ be with you.
