Mark 9:20-29 NRSVue

20And they brought the boy to him. When the spirit saw him, immediately it convulsed the boy, and he fell on the ground and rolled about, foaming at the mouth. 21Jesus asked the father, “How long has this been happening to him?” And he said, “From childhood. 22It has often cast him into the fire and into the water, to destroy him; but if you are able to do anything, help us! Have compassion on us!” 23Jesus said to him, “If you are able! All things can be done for the one who believes.” 24Immediately the father of the child cried out, “I believe; help my unbelief!” 25When Jesus saw that a crowd came running together, he rebuked the unclean spirit, saying to it, “You spirit that keeps this boy from speaking and hearing, I command you, come out of him, and never enter him again!” 26After crying out and convulsing him terribly, it came out, and the boy was like a corpse, so that most of them said, “He is dead.” 27But Jesus took him by the hand and lifted him up, and he was able to stand. 28When he had entered the house, his disciples asked him privately, “Why could we not cast it out?” 29He said to them, “This kind can come out only through prayer.”
