¹⁷ One of the men in the crowd spoke up and said, “Teacher, I brought my son so you could heal him. He is possessed by an evil spirit that won’t let him talk. ¹⁸ And whenever this spirit seizes him, it throws him violently to the ground. Then he foams at the mouth and grinds his teeth and becomes rigid. So I asked your disciples to cast out the evil spirit, but they couldn’t do it.”

¹⁹ Jesus said to them, “You faithless people! How long must I be with you? How long must I put up with you? Bring the boy to me.”

²⁰ So they brought the boy. But when the evil spirit saw Jesus, it threw the child into a violent convulsion, and he fell to the ground, writhing and foaming at the mouth.

²¹ “How long has this been happening?” Jesus asked the boy’s father.

He replied, “Since he was a little boy. ²² The spirit often throws him into the fire or into water, trying to kill him. Have mercy on us and help us, if you can.”

²³ “What do you mean, ‘If I can’?” Jesus asked. “Anything is possible if a person believes.”

²⁴ The father instantly cried out, “I do believe, but help me overcome my unbelief!”

²⁵ When Jesus saw that the crowd of onlookers was growing, he rebuked the evil^f] spirit. “Listen, you spirit that makes this boy unable to hear and speak,” he said. “I command you to come out of this child and never enter him again!”

²⁶ Then the spirit screamed and threw the boy into another violent convulsion and left him. The boy appeared to be dead. A murmur ran through the crowd as people said, “He’s dead.” ²⁷ But Jesus took him by the hand and helped him to his feet, and he stood up.

²⁸ Afterward, when Jesus was alone in the house with his disciples, they asked him, “Why couldn’t we cast out that evil spirit?”

²⁹ Jesus replied, “This kind can be cast out only by prayer.
