Mark 9:21-27 NIV
Jesus asked the boy’s father, “How long has he been like this?”
“From childhood,” he answered. “It has often thrown him into fire or water to kill him. But if you can do anything, take pity on us and help us.”
“ ‘If you can’?” said Jesus. “Everything is possible for one who believes.”
Immediately the boy’s father exclaimed, “I do believe; help me overcome my unbelief!”
When Jesus saw that a crowd was running to the scene, he rebuked the impure spirit. “You deaf and mute spirit,” he said, “I command you, come out of him and never enter him again.”
The spirit shrieked, convulsed him violently and came out. The boy looked so much like a corpse that many said, “He’s dead.” But Jesus took him by the hand and lifted him to his feet, and he stood up.
