Commentary on Matthew 17 verses 14–21
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 (Mat 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, Pe1 5:8.
2.The disappointment of his expectation from the disciples (Mat 17:16); I brought him to thy disciples, and they could not cured him. Christ gave his disciples power to cast out devils (Mat 10:1, Mat 10:8), and therein they were successful (Luk 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 (Mat 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 Mar 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 (Psa 95:9), forward, for in them is no faith, Deu 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, Act 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 (Mat 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 (Mat 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, Mat 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, Mat 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 (Mat 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.
"And when they were come to the multitude, there came to Him a man, kneeling down to Him, and saying, Lord, have mercy on my son, for he is lunatic, and sore vexed; for ofttimes he falleth into the fire, and oft into the water. And I brought him unto Thy disciples, and they could not cure him."
This man the Scripture signifies to be exceedingly weak in faith; and this is many ways evident; from Christ's saying, "All things are possible to him that believeth;" from the saying of the man himself that approached, "Help Thou mine unbelief:" from Christ's commanding the devil to "enter no more into him;" and from the man's saying again to Christ, "If Thou canst." "Yet if his unbelief was the cause," it may be said, "that the devil went not out, why doth He blame the disciples?" Signifying, that even without persons to bring the sick in faith, they might in many instances work a cure. For as the faith of the person presenting oftentimes availed for receiving the cure, even from inferior ministers; so the power of the doers oftentimes sufficed, even without belief in those who came to work the miracle.
And both these things are signified in the Scripture. For both they of the company of Cornelius by their faith drew unto themselves the grace of the Spirit; and in the case of Eliseus again, when none had believed, a dead man rose again. For as to those that cast him down, not for faith but for cowardice did they cast him, unintentionally and by chance, for fear of the band of robbers, and so they fled: while the person himself that was cast in was dead, yet by the mere virtue of the holy body the dead man arose.
Whence it is clear in this case, that even the disciples were weak; but not all; for the pillars were not present there. And see this man's want of consideration, from another circumstance again, how before the multitude he pleads to Jesus against His disciples, saying, "I brought him to Thy disciples, and they could not cure him."
But He, acquitting them of the charges before the people, imputes the greater part to him. For, "O faithless and perverse generation," these are His words, "how long shall I be with you?" not aiming at his person only, lest He should confound the man, but also at all the Jews. For indeed many of those present might probably be offended, and have undue thoughts of them.
But when He said, "How long shall I be with you," He indicates again death to be welcome to Him, and the thing an object of desire, and His departure longed for, and that not crucifixion, but being with them, is grievous.
He stopped not however at the accusations; but what saith He? "Bring him hither to me." And Himself moreover asks him, "how long time he is thus;" both making a plea for His disciples, and leading the other to a good hope, and that he might believe in his attaining deliverance from the evil.
And He suffers him to be torn, not for display (accordingly, when a crowd began to gather, He proceeded to rebuke him), but for the father's own sake, that when he should see the evil spirit disturbed at Christ's mere call, so at least, if in no other way, he might be led to believe the coming miracle.
And because he had said, "Of a child," and, "If thou canst help me," Christ saith, "To him that believeth, all things are possible," again giving the complaint a turn against him. And whereas when the leper said, "If Thou wilt, Thou canst make me clean," bearing witness to His authority Christ commending him, and confirming His words, said, "I will, be thou clean;" in this man's case, upon his uttering a speech in no way worthy of His power,-"If Thou canst, help me,"-see how He corrects it, as not rightly spoken. For what saith He? "If thou canst believe, all things are possible to him that believeth." What He saith is like this: "Such abundance of power is with me, that I can even make others work these miracles. So that if thou believe as one ought, even thou thyself art able," saith He, "to heal both this one, and many others." And having thus said, He set free the possessed of the devil.
But do thou not only from this observe His providence and His beneficence, but also from that other time, during which He allowed the devil to be in him. Since surely, unless the man had been favored with much providential care even then, he would have perished long ago; for "it cast him both into the fire," so it is said, "and into the water." And he that dared this would assuredly have destroyed the man too, unless even in so great madness God had put on him His strong curb: as indeed was the case with those naked men that were running in the deserts and cutting themselves with stones.
And if he call him "a lunatic," trouble not thyself at all, for it is the father of the possessed who speaks the word. How then saith the evangelist also, "He healed many that were lunatic?" Denominating them according to the impression of the multitude. For the evil spirit, to bring a reproach upon nature, both attacks them that are seized, and lets them go, according to the courses of the moon; not as though that were the worker of it;-away with the thought;-but himself craftily doing this to bring a reproach on nature. And an erroneous opinion hath gotten ground among the simple, and by this name do they call such evil spirits, being deceived; for this is by no means true.
is to be noted, that were not man fortified here by Providence, he would long since have perished; for the dæmons who cast him into the fire, and into the water, would have killed him outright, had God not restrained him.
See herein also his folly, in that before the multitude he appeals to Jesus against His disciples. But He clears them from shame, inputing their failure to the patient himself; for many things show that he was weak in faith. But He addresses His reproof not to the man singly, that He may not trouble him, but to the Jews in general. For many of those present, it is likely, had improper thoughts concerning the disciples, and therefore it follows, Jesus answered and said, O faithless and perverse generation, how long shall I be with you, how long shall I suffer you? His How long shall I be with you? shows that death was desired by Him, and that He longed for His withdrawal.
When He had vindicated His disciples, He leads the boy's father to a cheering hope of believing that he shall be delivered out of this evil and that the father might be led to believe the miracle that was coming, seeing the dæmons was disturbed even when the child was only called;
(Verse 16.) But Jesus replied, saying: O unbelieving and perverse generation, how long shall I be with you? How long shall I bear with you? Bring him here to me. Not because he was overcome by weariness, and gentle and meek, who did not open his mouth like a lamb before the shearer (Isaiah 53), nor did he burst forth in words of fury; but because, in the likeness of a physician, if he sees a sick person behaving contrary to his instructions, he may say: How long shall I come to your house, until I lose the skill of my craft, you commanding one thing and doing another? But he is not angry with the man, but with the fault; and through one man he accuses the Jews of unfaithfulness, so that he immediately says: Bring him here to me.
In saying, And I brought him to thy disciples, and they could not heal him, he covertly accuses the Apostles, whereas that a cure is impossible is sometimes the effect not of want of power in those that undertake it, but of want of faith in those that are to be healed,
Not that we must think that He was overcome by weariness of them, and that The meek and gentle broke out into words of wrath, but as a physician who might see the sick man acting against his injunctions, would say, How long shall I frequent your chamber? How long throw away the exercise of my skill, while I prescribe one thing, and you do another? That it is the sin, and not the man with whom He is angry, and that in the person of this one man He convicts the Jews of unbelief, is clear from what He adds, Bring him to me.
He rebuked him, that is, not the sufferer, but the dæmons.
Or, His reproof was to the child, because for his sins he had been seized on by the dæmons.
It may be known also, that not now for the first time, but of a long time, the Lord had borne the Jews' stubbornness, whence He says, How long shall I suffer you? because I have now a long while endured your iniquities, and ye are unworthy of My presence.
In which deed He left an example to preachers to attack sins, but to assist men.
The lunatic is figuratively one who is hurried into fresh vices every hour, one while is cast into the fire, with which the hearts of the adulterers burn; or again into the waters of pleasures or lusts, which yet have not strength to quench love. (Hos. 7:4, 6.)
Do you see how the man has shifted the blame for his own lack of faith upon the disciples, saying that they were too weak to heal? The Lord, therefore, shames him for accusing the disciples, saying, O faithless generation, that is, "It is not so much the fault of the weakness of the disciples as it is of your lack of faith, which, being great, has prevailed over the equal measure of their strength." He rebukes not only this man, but everyone who lacks faith, even the bystanders. By saying, How long shall I be with you? Christ shows that He longs for the Passion upon the Cross and His departure from them. For He is saying, "How long shall I live among scoffers and unbelievers? And Jesus rebuked him—whom? The man who was lunatic. From this it appears that he, too, lacked faith and his lack of faith had given occasion for the demon to enter him.

SUMMARY
Matthew 17:16 recounts the frustrated plea of a father whose demon-possessed son could not be healed by Jesus' disciples. This pivotal moment, occurring immediately after the Transfiguration, starkly contrasts Jesus' divine power with the disciples' spiritual limitations, setting the stage for Jesus' subsequent teaching on the necessity of faith, prayer, and fasting for overcoming formidable spiritual strongholds.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
The verse employs Contrast by juxtaposing the father's hope and the disciples' inability, which is further amplified by the immediate preceding narrative of Jesus' Transfiguration, where His divine power was on full display. The scene also utilizes Foreshadowing, as the disciples' failure here directly precedes and necessitates Jesus' teaching on the power of faith and prayer in the following verses. There is also an element of Irony, as those who had been given authority to cast out demons (e.g., Matthew 10:8) are now powerless in a critical moment, highlighting that spiritual authority is not a static possession but requires ongoing spiritual vitality and dependence.
THEOLOGICAL AND THEMATIC CONNECTIONS
Matthew 17:16 is a profound theological statement on the nature of spiritual authority and the source of true power. It underscores that even those commissioned by Christ can face spiritual impasses when their faith is insufficient or when they neglect the spiritual disciplines necessary to wield divine power effectively. The disciples' failure serves as a crucial lesson not only for them but for all believers, reminding us that our effectiveness in ministry is not inherent but is derived from an active, dependent relationship with God. It highlights the reality that some spiritual battles require a deeper level of spiritual engagement than others, challenging believers to cultivate a robust and unwavering faith.
REFLECTION AND APPLICATION
Matthew 17:16 serves as a sobering reminder that even in our earnest desire to serve God and help others, we will encounter situations where our own strength, wisdom, or past successes prove insufficient. The disciples, despite their close proximity to Jesus and previous empowerment, found themselves utterly powerless before a formidable spiritual adversary. This should humble us, prompting us to recognize that true spiritual power is not a commodity we possess, but a divine enablement we receive through active, dependent faith in Christ. When we face seemingly insurmountable obstacles—whether in our personal lives, our ministries, or the lives of those we seek to help—this verse calls us to examine the depth of our faith, our reliance on God, and our commitment to spiritual disciplines like prayer and fasting, which Jesus later highlights as essential for such breakthroughs. It encourages us to shift our focus from our own capabilities to the infinite power of God, trusting Him to accomplish what is impossible for us.
Questions for Reflection
FAQ
Why were the disciples unable to cure the boy, despite having been given authority by Jesus?
Answer: The disciples' inability to cure the demon-possessed boy, as stated in Matthew 17:16, stemmed from a deficiency in their faith and a lack of understanding regarding the spiritual nature of this particular battle. Jesus later explains in Matthew 17:20 that their failure was due to their "little faith." He further elaborates in Matthew 17:21 (though this verse is absent in some ancient manuscripts, its thematic truth is supported elsewhere) that "this kind does not come out except by prayer and fasting." This suggests that while they had been given general authority, certain spiritual strongholds require a heightened level of spiritual discipline, dependence, and unwavering faith, which they lacked in that moment. Their previous successes may have led to a degree of self-reliance rather than absolute dependence on God.
CHRIST-CENTERED FULFILLMENT
Matthew 17:16, highlighting the disciples' failure, powerfully underscores the unique and absolute authority of Jesus Christ. Their inability to cast out the demon serves as a dramatic foil, setting the stage for Jesus to demonstrate His unparalleled power and compassion. Unlike His disciples, Jesus never fails in the face of spiritual darkness. He is the ultimate Healer and Deliverer, the one who possesses all authority in heaven and on earth (Matthew 28:18). This incident points forward to Christ's ultimate victory over all demonic powers and the forces of sin and death through His death and resurrection. He is the Lamb of God who takes away the sin of the world, and through His finished work, He provides the power for believers to overcome spiritual strongholds, not by their own might, but by relying on His indwelling Spirit (Philippians 4:13). The disciples' failure in Matthew 17:16 ultimately magnifies Christ as the only one truly capable of delivering humanity from the bondage of sin and evil, offering true freedom and healing to all who believe (John 8:36).
