3. For though we live in the world, we do not wage war as the world does.
6. And we will be ready to punish every act of disobedience, once your obedience is complete.
9. I do not want to seem to be trying to frighten you with my letters.
17. But, "Let him who boasts boast in the Lord."
18. For it is not the one who commends himself who is approved, but the one whom the Lord commends.
