Matthew 18:15-17

“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.
