17 A man in the crowd answered, “Teacher, I brought you my son, who is possessed by a spirit that has robbed him of speech.
18 Whenever 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 “O unbelieving generation,” Jesus replied, “how long shall I stay with you? How long shall I put up with you? Bring the boy to me.”
20 So 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.
21
Jesus 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 him who believes.”
24 Immediately the boy’s father exclaimed, “I do believe; help me overcome my unbelief!”
25 When Jesus saw that a crowd was running to the scene, he rebuked the evil spirit. “You deaf and mute spirit,” he said, “I command you, come out of him and never enter him again.”
26 The spirit shrieked, convulsed him violently and came out. The boy looked so much like a corpse that many said, “He’s dead.”
27 But Jesus took him by the hand and lifted him to his feet, and he stood up.
