Mark 9:21-24

21And he asked his father, How long is it since this came to him? And he said, From a child. 22And often it hath cast him into the fire, and into the waters, to destroy him: but if thou canst do any thing, have compassion on us, and help us. 23Jesus said to him, If thou canst believe, all things are possible to him that believeth. 24And immediately the father of the child cried out, and said with tears, Lord, I believe; help thou my unbelief.
