19 "You unbelieving people!" Jesus replied. "How long do I have to stay with you? How long do I have to put up with you? Bring the boy to me."
20 So they brought him. As soon as the spirit saw Jesus, it threw the boy into a fit. He fell to the ground. He rolled around and foamed at the mouth.
21 Jesus asked the boy's father, "How long has he been like this?" "Since he was a child," he answered.
22 "The spirit has often thrown him into fire or water to kill him. But if you can do anything, take pity on us. Please help us."
23 " 'If you can'?" said Jesus. "Everything is possible for the one who believes."
24 Right away the boy's father cried out, "I do believe! Help me overcome my unbelief!"
25 Jesus saw that a crowd was running over to see what was happening. Then he ordered the evil spirit to leave the boy. "You spirit that makes him unable to hear and speak!" he said. "I command you, come out of him. Never enter him again."
