37 On the next day, when they had come down from the mountain, a great crowd met him. 38 And behold, a man from the crowd cried out, "Teacher, I beg you to look at my son, for he is my only child. 39 And behold, a spirit seizes him, and he suddenly cries out. It convulses him so that he foams at the mouth, and shatters him, and will hardly leave him. 40 And I begged your disciples to cast it out, but they could not." 41 Jesus answered, "O faithless and twisted generation, how long am I to be with you and bear with you? Bring your son here." 42 While he was coming, the demon threw him to the ground and convulsed him. But Jesus rebuked the unclean spirit and 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.
