Mat Matthew, chapter The Gospel According to Matthew, chapter 17
Jesus healed an epileptic boy, and he rebuked his disciples for not having enough faith to do miracles.
Matthew 17:14-21
He answered us, “It is because you did not believe very much in God’s power. Think about this: Mustard seeds are very small, but in this area they grow and produce large [MET] plants. Similarly, if your faith grows until you truly believe that God will do what you ask him to, you will be able to do anything [LIT]! You could even say to this hill, ‘Move from here to there!’ and it would go where you told it to go.”Mat 21:21; Mrk 9:23; Mrk 11:23; Luk 17:6; Mrk 9:29
