Mark 9:20-22

20So the people brought the boy to Jesus. When the bad spirit saw Jesus, it immediately caused the boy's body to shake strongly. The boy fell onto the ground and he rolled about. Water was coming from his mouth.

21Jesus asked the boy's father, ‘How long has he been like this?’ ‘He has been like this since he was a small boy,’ the father replied.

22‘Often the spirit has caused him to fall into the fire or into water. It is trying to kill him. Please be kind to us. If you can do anything, help us!’
