We have here the miraculous cure of a child that was lunatic and vexed with a devil. Observe,
I. A melancholy representation of the case of this child, made to Christ by the afflicted father. This was immediately upon his coming down from the mountain where he was transfigured. Note, Christ’s glories do not make him unmindful of us and of our wants and miseries. Christ, when he came down from the mount, where had conversation with Moses and Elias, did not take state upon him, but was as easy of access, as ready to poor beggars, and as familiar with the multitude, as ever he used to be. This poor man’s address was very importunate; he came kneeling to Christ. Note, Sense of misery will bring people to their knees. Those who see their need of Christ will be earnest, will be in good earnest, in their applications to him; and he delights to be thus wrestled with.
Two things the father of the child complains of.
1. The distress of his child (Matt. 17:15); Lord have mercy on my son. The affliction of the children cannot but affect the tender parents, for they are pieces of themselves. And the case of afflicted children should be presented to God by faithful and fervent prayer. This child’s distemper, probably, disabled him to pray for himself. Note, Parents are doubly concerned to pray for their children, not only that are weak and cannot, but much more that are wicked and will not, pray for themselves. Now, (1.). The nature of this child’s disease was very sad; He was lunatic and sore vexed. A lunatic is properly one whose distemper lies in the brain, and returns with the change of the moon. The devil, by the divine permission, either caused this distemper, or at least concurred with it, to heighten and aggravate it. The child had the falling-sickness, and the hand of Satan was in it; by it he tormented then, and made it much more grievous than ordinarily it is. Those whom Satan got possession of, he afflicted by those diseases of the body which do most affect the mind; for it is the soul that he aims to do mischief to. The father, in his complain, saith, He is lunatic, taking notice of the effect; but Christ, in the cure, rebuked the devil, and so struck at the cause. Thus he doth in spiritual cures. (2.) The effects of the disease were very deplorable; He oft falls into the fire, and into the water. If the force of the disease made him to fall, the malice of the devil made him to fall into the fire or water; so mischievous is he where he gains possession and power in any soul. He seeks to devour, 1 Pet. 5:8.
2. The disappointment of his expectation from the disciples (Matt. 17:16); I brought him to thy disciples, and they could not cured him. Christ gave his disciples power to cast out devils (Matt. 10:1, 8), and therein they were successful (Luke 10:17); yet at this time they failed in the operation, though there were nine of them together, and before a great multitude. Christ permitted this, (1.) To keep them humble, and to show their dependence upon him, that without him they could do nothing. (2.) To glorify himself and his own power. It is for the honour of Christ to come in with help at a dead-lift, when other helpers cannot help. Elisha’s staff in Gehazi’s hand will not raise the child: he must come himself. Note, There are some special favours which Christ reserves the bestowment of to himself; and sometimes he keeps the cistern empty; that he may bring us to himself, the Fountain. But the failures of instruments shall not hinder the operations of his grace, which will work, if not by them, yet without them.
II. The rebukes that Christ gave to the people first, and then to the devil.
1. He chid those about him (Matt. 17:17); O faithless and perverse generation! This is not spoken to the disciples, but to the people, and perhaps especially to the scribes, who are mentioned in Mark 9:14; and who, as it should seem, insulted over the disciples, because they had now met with a case that was too hard for them. Christ himself could not do many mighty works among a people in whom unbelief reigned. It was here owing to the faithlessness of this generation, that they could not obtain those blessings from God, which otherwise they might have had; as it was owing to the weakness of the disciples’ faith, that they could not do those works for God, which otherwise they might have done. They were faithless and perverse. Note, Those that are faithless will be perverse; and perverseness is sin in its worst colours. Faith is compliance with God, unbelief is opposition and contradiction to God. Israel of old was perverse, because faithless (Ps. 95:9), forward, for in them is no faith, Deut. 32:20.
Two things he upbraids them with. (1.) His presence with them so long; “How long shall I be with you? Will you always need my bodily presence, and never come to such maturity as to be fit to be left, the people to the conduct of the disciples, and the disciples to the conduct of the Spirit and of their commission? Must the child be always carried, and will it never learn to go alone?” (2.) His patience with them so long; How long shall I suffer you? Note, [1.] The faithlessness and perverseness of those who enjoy the means of grace are a great grief to the Lord Jesus. Thus did he suffer the manners of Israel of old, Acts 13:18. [2.] The longer Christ has borne with a perverse and faithless people, the more he is displeased with their perverseness and unbelief; and he is God, and not man, else he would not suffer so long, nor bear so much, as he doth.
2. He cured the child, and set him to-rights again. He called, Bring him hither to me. Though the people were perverse, and Christ was provoked, yet care was taken of the child. Note, Though Christ may be angry, he is never unkind, nor doth he, in the greatest of his displeasure, shut up the bowels of his compassion from the miserable; Bring him to me. Note, When all other helps and succours fail, we are welcome to Christ, and may be confident in him and in his power and goodness.
See here an emblem of Christ’s undertaking as our Redeemer.
(1.) He breaks the power of Satan (Matt. 17:18); Jesus rebuked the devil, as one having authority, who could back with force his word of command. Note, Christ’s victories over Satan are obtained by the power of his word, the sword that comes out of his mouth, Rev. 19:21. Satan cannot stand before the rebukes of Christ, though his possession has been ever so long. It is comfortable to those who are wrestling with principalities and powers, that Christ hath spoiled them, Col. 2:15. The lion of the tribe of Judah will be too hard for the roaring lion that seeks to devour.
(2.) He redresses the grievances of the children of men; The child was cured from that very hour. It was an immediate cure, and a perfect one. This is an encouragement to parents to bring their children to Christ, whose souls are under Satan’s power; he is able to heal them, and as willing as he is able. Not only bring them to Christ by prayer, but bring them to the word of Christ, the ordinary means by which Satan’s strongholds are demolished in the soul. Christ’s rebukes, brought home to the heart, will ruin Satan’s power there.
III. Christ’s discourse with his disciples hereupon.
1. They ask the reason why they could not cast out the devil at this time (Matt. 17:19); They came to Jesus apart. Note, Ministers, who are to deal for Christ in public, have need to keep up a private communion with him, that they may in secret, where no eye sees, bewail their weakness and straitness, their follies and infirmities, in their public performances, and enquire into the cause of them. We should make use of the liberty of access we have to Jesus apart, where we may be free and particular with him. Such questions as the disciples put to Christ, we should put to ourselves, in communing with our own hearts upon our beds; Why were we so dull and careless at such a time? Why came we so much short in such a duty? That which is amiss may, when found out, be amended.
2. Christ gives them two reasons why they failed.
(1.) It was because of their unbelief, Matt. 17:20. When he spake to the father of the child and to the people, he charged it upon their unbelief; when he spake to his disciples, he charged it upon theirs; for the truth was, there were faults on both sides; but we are more concerned to hear of our own faults than of other people’s, and to impute what is amiss to ourselves than to others. When the preaching of the word seems not to be so successful as sometimes it has been, the people are apt to lay all the fault upon the ministers, and the ministers upon the people; whereas, it is more becoming for each to own his own faultiness, and to say, “It is owing to me.” Ministers, in reproving, must learn thus to give to each his portion of the word; and to take people off from judging others, by teaching all to judge themselves; It is because of your unbelief. Though they had faith, yet that faith was weak and ineffectual. Note, [1.] As far as faith falls short of its due strength, vigour, and activity, it may truly be said, “There is unbelief.” Many are chargeable with unbelief, who yet are not to be called unbelievers. [2.] It is because of our unbelief, that we bring so little to pass in religion, and so often miscarry, and come short, in that which is good.
Our Lord Jesus takes this occasion to show them the power of faith, that they might not be defective in that, another time, as they were now; If ye have faith as a grain of mustard-seed, ye shall do wonders, Matt. 17:20. Some make the comparison to refer to the quality of the mustard-seed, which is, when bruised, sharp and penetrating; “If you have an active growing faith, not dead, flat, or insipid, you will not be baffled thus.” But it rather refers to the quantity; “If you had but a grain of true faith, though so little that it were like that which is the least of all seeds, you would do wonders.” Faith in general is a firm assent to, a compliance with, and a confidence in, all divine revelation. The faith here required, is that which had for its object that particular revelation by which Christ gave his disciples power to work miracles in his name, for the confirmation of the doctrine they preached. It was a faith in this revelation that they were defective in; either doubting the validity of their commission, or fearing that it expired with their first mission, and was not to continue when they were returning to their Master; or that it was some way or other forfeited or withdrawn. Perhaps their Master’s absence with the three chief of his disciples, with a charge to the rest not to follow them, might occasion some doubts concerning their power, or rather the power of the Lord with them, to do this; however, there were not, at present, such a strong actual dependence upon, and confidence in, the promise of Christ’s presence with them, as there should have been. It is good for us to be diffident of ourselves and of our own strength; but it is displeasing to Christ, when we distrust any power derived from him or granted by him.
If ye have ever so little of this faith in sincerity, if ye truly rely upon the powers committed to you, ye shall say to this mountain, Remove. This is a proverbial expression, denoting that which follows, and no more, Nothing shall be impossible to you. They had a full commission, among other things, to cast out devils without exception; but, this devil being more than ordinarily malicious and inveterate, they distrusted the power they had received, and so failed. To convince them of this, Christ shows them what they might have done. Note, An active faith can remove mountains, not of itself, but in the virtue of a divine power engaged by a divine promise, both which faith fastens upon.
(2.) Because there was something in the kind of the malady, which rendered the cure more than ordinarily difficult (Matt. 17:21); “This kind goes not out but by prayer and fasting. This possession, which works by a falling-sickness, or this kind of devils that are thus furious, is not cast out ordinarily but by great acts of devotion, and wherein ye were defective.” Note, [1.] Though the adversaries we wrestle, be all principalities and powers, yet some are stronger than others, and their power more hardly broken. [2.] The extraordinary power of Satan must not discourage our faith, but quicken us to a greater intenseness in the acting of it, and more earnestness in praying to God for the increase of it; so some understand it here; “This kind of faith (which removeth mountains) doth not proceed, is not obtained, from God, nor is it carried up to its full growth, nor drawn out into act and exercise, but by earnest prayer.” [3.] Fasting and prayer are proper means for the bringing down of Satan’s power against us, and the fetching in of divine power to our assistance. Fasting is of use to put an edge upon prayer; it is an evidence and instance of humiliation which is necessary in prayer, and is a means of mortifying some corrupt habits, and of disposing the body to serve the soul in prayer. When the devil’s interest in the soul is confirmed by the temper and constitution of the body, fasting must be joined with prayer, to keep under the body.
