When they came to the crowd, a man came to him, knelt before him, and said, “Lord, have mercy on my son, because he has seizures and suffers terribly, for he often falls into the fire and into the water. I brought him to your disciples, but they were not able to heal him.” Jesus answered, “You unbelieving and perverse generation! How much longer must I be with you? How much longer must I endure you? Bring him here to me.” Then Jesus rebuked the demon and it came out of him, and the boy was healed from that moment.
A member of the crowd said to him, “Teacher, I brought you my son, who is possessed by a spirit that makes him mute. Whenever it seizes him, it throws him down, and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, but they were not able to do so.” He answered them, “You unbelieving generation! How much longer must I be with you? How much longer must I endure you? Bring him to me.” So they brought the boy to him. When the spirit saw him, it immediately threw the boy into a convulsion. He fell on the ground and rolled around, foaming at the mouth. Jesus asked his father, “How long has this been happening to him?” And he said, “From childhood. It has often thrown him into fire or water to destroy him. But if you are able to do anything, have compassion on us and help us.” Then Jesus said to him, “‘If you are able?’ All things are possible for the one who believes.” Immediately the father of the boy cried out and said, “I believe; help my unbelief!”
Now when Jesus saw that a crowd was quickly gathering, he rebuked the unclean spirit, saying to it, “Mute and deaf spirit, I command you, come out of him and never enter him again.” It shrieked, threw him into terrible convulsions, and came out. The boy looked so much like a corpse that many said, “He is dead!” But Jesus gently took his hand and raised him to his feet, and he stood up.
Then, after he went into the house, his disciples asked him privately, “Why couldn’t we cast it out?” He told them, “This kind can come out only by prayer.”
Then a man from the crowd cried out, “Teacher, I beg you to look at my son—he is my only child! A spirit seizes him, and he suddenly screams; it throws him into convulsions and causes him to foam at the mouth. It hardly ever leaves him alone, torturing him severely. I begged your disciples to cast it out, but they could not do so.” Jesus answered, “You unbelieving and perverse generation! How much longer must I be with you and endure you? Bring your son here.” As the boy was approaching, the demon threw him to the ground and shook him with convulsions. But Jesus rebuked the unclean spirit, healed the boy, and gave him back to his father. Then they were all astonished at the mighty power of God.
