Mark 9:20-26
9:20 So they brought the boy to him. When the spirit saw him, it immediately threw the boy into a convulsion. He fell on the ground and rolled around, foaming at the mouth.
9:21 Jesus asked his father, “How long has this been happening to him?” And he said, “From childhood.
9:22 It has often thrown him into fire or water to destroy him. But if you are able to do anything, have compassion on us and help us.”
9:23 Then Jesus said to him, “‘If you are able?’ All things are possible for the one who believes.”
9:24 Immediately the father of the boy cried out and said, “I believe; help my unbelief!”
9:25 Now when Jesus saw that a crowd was quickly gathering, he rebuked the unclean spirit, saying to it, “Mute and deaf spirit, I command you, come out of him and never enter him again.”
9:26 It shrieked, threw him into terrible convulsions, and came out. The boy looked so much like a corpse that many said, “He is dead!”
