“And when they were come to the multitude, there came to him a certain man, and, fell down at his feet, And said, Master, have pity on my son: for he is lunatic, and is sore vexed: for oft times he falleth into the fire, and oft times into the water. And I brought him to thy disciples, and they could not heal him. Then Jesus answered, and said, O generation faithless, and crooked, how long now shall I be with you! how long now shall I suffer you! bring him hither to me. And Jesus rebuked the devil, and he went out of him: and the child was healed at that hour.
Then came the disciples to Jesus apart, and said, Why could not we cast him out?
And Jesus said unto them, Because of your unbelief: for verily I say unto you, if ye have faith as much as is a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place, and it shall remove: and nothing shall be impossible unto you.
Howbeit this kind goeth not out, but by prayer and fasting” Matthew 17:14-21 (GNV).
