Mark 9:14-22

Now when they came down the mountain to the other nine disciples, they noticed a large crowd of people gathered around them, with the religious scholars arguing with them. The crowd was astonished to see Jesus himself walking toward them, so they immediately ran to welcome him. “What are you arguing about with the religious scholars?” he asked them. A man spoke up out of the crowd. “Teacher,” he said, “I have a son possessed by a demon that makes him mute. I brought him here to you, Jesus. Whenever the demon takes control of him, it knocks him down, and he foams at the mouth and gnashes his teeth, and his body becomes stiff as a board. I brought him to your disciples, hoping they could deliver him, but they were not able to do it.” Jesus said to the crowd, “Why are you such a faithless people? How much longer must I remain with you and put up with your unbelief? Now, bring the boy to me.” So they brought him to Jesus. As soon as the demon saw him, it threw the boy into convulsions. He fell to the ground, rolling around and foaming at the mouth. Jesus turned to the father and asked, “How long has your son been tormented like this?” “Since childhood,” he replied. “It tries over and over to kill him by throwing him into fire or into the water. But please, if you’re able to do something, anything—have compassion on us and help us!”
