Mark 11:27

Therefore I tell you, all things whatever you pray and ask for, believe that you have received them, and you shall have them.

Whenever you stand praying, forgive, if you have anything against anyone; so that your Father, who is in heaven, may also forgive you your transgressions.

But if you do not forgive, neither will your Father in heaven forgive your transgressions.”

and they began saying to him, “By what authority do you do these things? Or who gave you this authority to do these things?”

Jesus said to them, “I will ask you one question. Answer me, and I will tell you by what authority I do these things.

The baptism of John—was it from heaven, or from men? Answer me.”
