Matthew 17:15-18

said, “Lord, have mercy on my son, for he has seizures and he suffers terribly. For often he falls into the fire, and often into the water. And I brought him to your disciples, and they could not heal him.” And Jesus answered, “O faithless and twisted generation, how long am I to be with you? How long am I to bear with you? Bring him here to me.” And Jesus rebuked the demon, and it came out of him, and the boy was healed instantly.
