Yet another answered prayer from the 1857 Revival from the writings of Daniel Whittle:
“Last March, I requested you to pray for a dear friend in Massachusetts, who was deprived of her reason through sickness and great trouble. Give thanks unto God, she is fully restored.”
 Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.Matthew 17
 And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very 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 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.
