37 The next day, after they had come down the mountain, a large crowd met Jesus. 38 A man in the crowd called out to him, "Teacher, I beg you to look at my son, my only child. 39 An evil spirit keeps seizing him, making him scream. It throws him into convulsions so that he foams at the mouth. It batters him and hardly ever leaves him alone. 40 I begged your disciples to cast out the spirit, but they couldn't do it." 41 Jesus said, "You faithless and corrupt people! How long must I be with you and put up with you?" Then he said to the man, "Bring your son here." 42 As the boy came forward, the demon knocked him to the ground and threw him into a violent convulsion. But Jesus rebuked the evil spirit and healed the boy. Then he 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.
