Mark 9:17-27

17A man in the crowd answered, “Teacher, I brought you my son, who is possessed by a spirit that has robbed him of speech.

18Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth and becomes rigid. I asked your disciples to drive out the spirit, but they could not.”

19“You unbelieving generation,” Jesus replied, “how long shall I stay with you? How long shall I put up with you? Bring the boy to me.”

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

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

22“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.”

23“ ‘If you can’?” said Jesus. “Everything is possible for one who believes.”

24Immediately the boy’s father exclaimed, “I do believe; help me overcome my unbelief!”

25When 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.” 26The spirit shrieked, convulsed him violently and came out. The boy looked so much like a corpse that many said, “He’s dead.”

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