Matthew 18:18-20

18I tell you this: You will tell people here on earth what is right for them to do. And you will tell them what is not right for them to do. God in heaven will give you this authority. He will agree with what you say.

19Two people may agree together to ask God for something. If they agree like that, then my Father in heaven will give them what they ask for.

20Two or more people may meet together because they believe in me. If they do that, I will be there with them.’
