Luke 9:37-43

The next day, when they came down from the mountain, a large crowd met Jesus. A man in the crowd shouted to him, “Teacher, please come and look at my son, because he is my only child. An evil spirit seizes my son, and suddenly he screams. It causes him to lose control of himself and foam at the mouth. The evil spirit keeps on hurting him and almost never leaves him. I begged your followers to force the evil spirit out, but they could not do it.” Jesus answered, “You people have no faith, and your lives are all wrong. How long must I stay with you and put up with you? Bring your son here.” While the boy was coming, the demon threw him on the ground and made him lose control of himself. But Jesus gave a strong command to the evil spirit and healed the boy and gave him back to his father. All the people were amazed at the great power of God.
