15 "If a fellow believer hurts you, go and tell him - work it out between the two of you. If he listens, you've made a friend. If he won't listen, take one or two others along so that the presence of witnesses will keep things honest, and try again. If he still won't listen, tell the church. If he won't listen to the church, you'll have to start over from scratch, confront him with the need for repentance, and offer again God's forgiving love. 18 "Take this most seriously: A yes on earth is yes in heaven; a no on earth is no in heaven. What you say to one another is eternal. I mean this. When two of you get together on anything at all on earth and make a prayer of it, my Father in heaven goes into action. And when two or three of you are together because of me, you can be sure that I'll be there."
