Final Instructions and Greetings

17 I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. 18 For such persons do not serve our Lord Christ, but their own appetites, [1] and by smooth talk and flattery they deceive the hearts of the naive. 19 For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil. 20 The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus Christ be with you.
