Mark 9:29

Or else, the folly which is connected with the softness of the flesh, is healed by fasting; anger and laziness are healed by prayer. Each wound has its own medicine, which must be applied to it; that which is used for the heel will not cure the eye; by fasting, the passions of the body, by prayer, the plagues of the soul, are healed.

That is, the whole class of lunatics, or simply, of all persons possessed with devils. Both the man to be cured, and he who cures him, should fast; for a real prayer is offered up, when fasting is joined with prayer, when he who prays is sober and not heavy with food.

And he said unto them,.... Matthew, besides the following reason, assigns another, as given by our Lord, why they could not cast out the foul spirit, which was their unbelief; of which they were guilty in some sort, as well as the Jews, and the father of the child; but Mark omits it, and only relates this as the reason; this kind can come forth by nothing, but by prayer and fasting; which they had not observed; See Gill on Mat 17:21.

39 But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me. 40 For he that is not against us is on our part. Christ foretels his own approaching sufferings.

Prayer and fasting - See on Mat 17:21 (note). This demon may be considered as an emblem of deeply rooted vices, and inveterate habits, over which the conquest is not generally obtained, but through extraordinary humiliations. This case is related by both Matthew and Luke, but it is greatly amplified in Mark’s account, and many new circumstances related. Another proof that Mark did not abridge Matthew.

The contrast between these verses and those which precede them in the chapter is very striking. We pass from the mount of transfiguration to a melancholy history of the work of the devil. We come down from the vision of glory — to a conflict with Satanic possession. We change the blessed company of Moses and Elijah — for crude interaction with unbelieving Scribes.

"Howbeit this kind goeth not out but by prayer and fasting" (Mt 17:21), that is, though nothing is impossible to faith, yet such a height of faith as is requisite for such triumphs is not to be reached either in a moment or without effort--either with God in prayer or with ourselves in self-denying exercises.

The contrast between these verses and those which precede them in the chapter is very striking. We pass from the mount of transfiguration to a melancholy history of the work of the devil. We come down from the vision of glory — to a conflict with Satanic possession. We change the blessed company of Moses and Elijah — for crude interaction with unbelieving Scribes. We leave the foretaste of millennial glory, and the solemn voice of God the Father testifying to God the Son, and return once more to a scene of pain, weakness, and misery — a boy in agony of body, a father in deep distress, and a little band of feeble disciples restrained by Satan's power, and unable to give relief. The contrast, we must all feel, is very great. Yet it is but a faint emblem of the change of scene that Jesus voluntarily undertook to witness, when He first laid aside His glory and came into the world. And it is after all a vivid picture of the life of all true Christians. With them, as with their Master, work, conflict, and scenes of weakness and sorrow will always be the rule. With them too, visions of glory, foretastes of heaven, seasons on the mount, will always be the exception. Let us learn from these verses, how dependent Christ's disciples are on the company and help of their Master . We see this truth brought out in a striking manner in the scene which meets our Lord's eyes, when He came down from the mount. Like Moses, when he came down from Mount Sinai, He finds his little flock in confusion. He sees His nine apostles beset by a party of malicious Scribes, and baffled in an attempt to heal one who had been brought to them possessed with a devil. The very same disciples who a short time before had done many miracles and "cast out many devils," had now met with a case too hard for them. They were learning by humbling experience the great lesson, "without me you can do nothing."
