Mark 9:21-25

And He asked his father, “How long has this been happening to him?” And he said, “From childhood. It has often thrown him both into the fire and into the water to destroy him. But if You can do anything, take pity on us and help us!” And Jesus said to him, “ ‘If You can?’ All things are possible to him who believes.” Immediately the boy’s father cried out and said, “I do believe; help my unbelief.” When Jesus saw that a crowd was rapidly gathering, He rebuked the unclean spirit, saying to it, “You deaf and mute spirit, I command you, come out of him and do not enter him again.”
