17. Brothers and sisters, I want you to be very careful of those who cause arguments and hurt people’s faith by teaching things that are against what you learned. Stay away from them.
18. People like that are not serving our Lord Christ. They are only pleasing themselves. They use fancy talk and say nice things to fool those who don’t know about evil.
19. Everyone has heard that you do what you were taught, and I am very happy about that. But I want you to be wise about what is good and to know nothing about what is evil.
20. The God who brings peace will soon defeat Satan and give you power over him. The grace of our Lord Jesus be with you.
