Mark 9:16-29  New International Version

¹⁶ “What are you arguing with them about?” he asked.

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 “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.”

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.^(A)

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 one who believes.”^(B)

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,^(C) he rebuked the impure 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.

²⁸ After Jesus had gone indoors, his disciples asked him privately,^(D) “Why couldn’t we drive it out?”

²⁹ He replied, “This kind can come out only by prayer.^[a]”
