The Prayer of Faith
Faith is just believing that God will do what He said He will do. After Jesus had healed many people and done many miracles, He went back to His old hometown of Nazareth. But the people there did not believe that He could heal them. Jesus wanted to help them, but He could not because they did not believe!
Mark 11:23: Speak what you believe, without any doubt, and you shall have whatever you say!
Pray in faith, believing that God will do what He said He will do!
