6,7 "But if you give them a hard time, bullying or taking advantage of their simple trust, you’ll soon wish you hadn’t. You’d be better off dropped in the middle of the lake with a millstone around your neck. Doom to the world for giving these God-believing children a hard time! Hard times are inevitable, but you don’t have to make it worse—and it’s doomsday to you if you do.
15-17 "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.
