Mark 9:20-29

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 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. ”
