Mark 9:24-29

When he heard this, the boy’s father cried out with tears, saying, “I do believe, Lord; help my little faith!” Now when Jesus saw that the crowd was quickly growing larger, he commanded the demon, saying, “Deaf and mute spirit, I command you to come out of him and never enter him again!” The demon shrieked and threw the boy into terrible seizures and finally came out of him! As the boy lay there, looking like a corpse, everyone thought he was dead. But Jesus stooped down, gently took his hand, and raised him up to his feet, and he stood there completely set free! Afterwards, when Jesus arrived at the house, his disciples asked him in private, “Why couldn’t we cast out the demon?” He answered them, “This type of powerful spirit can only be cast out by fasting and prayer.”
