37 On the next day, when they had come down from the mountain, a great crowd met him. 38 Just then a man from the crowd shouted, "Teacher, I beg you to look at my son; he is my only child. 39 Suddenly a spirit seizes him, and all at once he shrieks. It convulses him until he foams at the mouth; it mauls him and will scarcely leave him. 40 I begged your disciples to cast it out, but they could not." 41 Jesus answered, "You faithless and perverse generation, how much longer must I be with you and bear with you? Bring your son here." 42 While he was coming, the demon dashed him to the ground in convulsions. But Jesus rebuked the unclean spirit, healed the boy, and gave him back to his father.

Commentary on Luke 9:37-42
(Read Luke 9:37-42)
How deplorable the case of this child! He was under the power of an evil spirit. Disease of that nature are more frightful than such as arise merely from natural causes. What mischief Satan does where he gets possession! But happy those that have access to Christ! He can do that for us which his disciples cannot. A word from Christ healed the child; and when our children recover from sickness, it is comfortable to receive them as healed by the hand of Christ.
