Mark 9:23-28 New American Standard Bible (NASB)

23. And Jesus said to him, " 'If You can?' All things are possible to him who believes."

24. Immediately the boy's father cried out and said, "I do believe; help my unbelief."

25. 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."

26. After crying out and throwing him into terrible convulsions, it came out; and the boy became so much like a corpse that most of them said, "He is dead!"

27. But Jesus took him by the hand and raised him; and he got up.

28. When He came into the house, His disciples began questioning Him privately, "Why could we not drive it out?"
