Mark 9:14-29

And when they came to the disciples, they saw a large crowd around them and scribes arguing with them. And immediately the whole crowd, when they saw him, were amazed, and ran up to him and greeted him. And he asked them, “What are you arguing about with them?” And one individual from the crowd answered him, “Teacher, I brought to you my son who has a spirit that makes him mute. And whenever it seizes him, it throws him down and he foams at the mouth and grinds his teeth and becomes paralyzed. And I told your disciples that they should expel it, and they were not able to do so. And he answered them and said, “O unbelieving generation! How long will I be with you? How long must I put up with you? Bring him to me!” And they brought him to him. And when he saw him, the spirit immediately convulsed him, and falling on the ground, he began to roll around, foaming at the mouth. And he asked his father how long it was since this had been happening to him. And he said, “From childhood. And often it has thrown him both into fire and into water, in order that it could destroy him. But if you are able to do anything, have compassion on us and help us!” But Jesus said to him, “If you are able! All things are possible for the one who believes!” Immediately the father of the child cried out and said, “I believe! Help my unbelief!” Now when Jesus saw that a crowd was running together, he rebuked the unclean spirit, saying to it, “Mute and deaf spirit, I command you, come out of him, and enter into him no more!” And it came out, screaming and convulsing him greatly, and he became as if he were dead, so that most of them said, “He has died!” But Jesus took hold of his hand and raised him up, and he stood up. And after he had entered into the house, his disciples asked him privately, “Why were we not able to expel it?” And he said to them, “This kind can come out by nothing except by prayer.”
