Matthew 18:12–20

What do you think? If a man has a hundred sheep and one of them goes astray, will he not leave the ninety-nine on the hills and go out to search for the one that is lost?

And if he finds it, truly I tell you, he rejoices more over that one sheep than over the ninety-nine that did not go astray.

In the same way, your Father in heaven is not willing that any of these little ones should perish.

If your brother sins against you, go and confront him privately. If he listens to you, you have won your brother over.

But if he will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’

If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, regard him as you would a pagan or a tax collector.

Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.

Again, I tell you truly that if two of you on the earth agree about anything you ask for, it will be done for you by My Father in heaven.

For where two or three gather together in My name, there am I with them.”
