Mark 9:20-24

20 And they brought him unto him: and when he saw him, straightway the spirit tare him; and he fell on the ground, and wallowed foaming.

21 And he asked his father, How long is it ago since this came unto him? And he said, Of a child.

22 And ofttimes 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.

23 Jesus said unto him, If thou canst believe, all things are possible to him that believeth.

24 And straightway the father of the child cried out, and said with tears, Lord, I believe; help thou mine unbelief.
