37 When they came down off the mountain the next day, a big crowd was there to meet them. 38 A man called from out of the crowd, "Please, please, Teacher, take a look at my son. He's my only child. 39 Often a spirit seizes him. Suddenly he's screaming, thrown into convulsions, his mouth foaming. And then it beats him black and blue before it leaves. 40 I asked your disciples to deliver him but they couldn't." 41 Jesus said, "What a generation! No sense of God! No focus to your lives! How many times do I have to go over these things? How much longer do I have to put up with this? Bring your son here." 42 While he was coming, the demon slammed him to the ground and threw him into convulsions. Jesus stepped in, ordered the vile spirit gone, healed the boy, and handed him back to his father.
43 They all shook their heads in wonder, astonished at God's greatness, God's majestic greatness.
44 "Treasure and ponder each of these next words: The Son of Man is about to be betrayed into human hands." 45 They didn't get what he was saying. It was like he was speaking a foreign language and they couldn't make heads or tails of it. But they were embarrassed to ask him what he meant.

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.
Commentary on Luke 9:43-50
(Read Luke 9:43-50)
This prediction of Christ's sufferings was plain enough, but the disciples would not understand it, because it agreed not with their notions. A little child is the emblem by which Christ teaches us simplicity and humility. What greater honour can any man attain to in this world, than to be received by men as a messenger of God and Christ; and to have God and Christ own themselves received and welcomed in him! If ever any society of Christians in this world, had reason to silence those not of their own communion, the twelve disciples at this time had; yet Christ warned them not to do the like again. Those may be found faithful followers of Christ, and may be accepted of him, who do not follow with us.
