Matthew 18:18-20 - Prohibiting And Permitting
18 I tell you truly, Whatever you prohibit on earth will be prohibited in heaven, and whatever you permit on earth will be permitted in heaven. 19 I tell you another thing: if two of you agree on earth about anything you pray for, it will be done for you by my Father in heaven. 20 For where two or three have gathered in my name, I am there among them."
