Mark 9:23

19 “O unbelieving generation!” Jesus replied. “How long must I remain with you? How long must I put up with you? Bring the boy to Me.”

20 So they brought him, and seeing Jesus, the spirit immediately threw the boy into a convulsion. He fell to the ground and rolled around, foaming at the mouth.

21 Jesus asked the boy’s father, “How long has this been with him?” “From childhood,” he said.

22 “It often throws him into the fire or into the water, trying to kill him. But if You can do anything, have compassion on us and help us.”

23 “If You can?” echoed Jesus. “All things are possible to him who believes!”

24 Immediately the boy’s father cried out, “I do believe; help my unbelief!”

25 When Jesus saw that a crowd had come running, He rebuked the unclean spirit. “You deaf and mute spirit,” He said, “I command you to come out and never enter him again.”

26 After shrieking and convulsing him violently, the spirit came out. The boy became like a corpse, so that many said, “He is dead.”

27 But Jesus took him by the hand and helped him to his feet, and he stood up.
