17. Brothers, I ask you to look out for those who cause people to be against each other and who upset other people’s faith. They are against the true teaching you learned. Stay away from them.
18. For such people are not serving our Lord Christ. They are only doing what pleases themselves. They use fancy talk and fine words to fool the minds of those who do not know about evil.
19. All the believers have heard that you obey. So I am very happy because of you. But I want you to be wise in what is good and innocent in what is evil.
