(22) If thou canst do any thing.--The words are spoken almost in the accents of despair. Could He, the Master, prevail where the disciples had failed?

9:14-29 The father of the suffering youth reflected on the want of power in the disciples; but Christ will have him reckon the disappointment to the want of faith. Very much is promised to our believing. If thou canst believe, it is possible that thy hard heart may be softened, thy spiritual diseases may be cured; and, weak as thou art, thou mayest be able to hold out to the end. Those that complain of unbelief, must look up to Christ for grace to help them against it, and his grace will be sufficient for them. Whom Christ cures, he cures effectually. But Satan is unwilling to be driven from those that have been long his slaves, and, when he cannot deceive or destroy the sinner, he will cause him all the terror that he can. The disciples must not think to do their work always with the same ease; some services call for more than ordinary pains.And ofttimes it hath cast him into the fire,.... When he has been near it; so that one part or other of his body has been scorched, or burnt, and his life in danger:

and into the waters to destroy him: when he has been near any brook, or river, it has thrown him into it, in order to drown him, as into the fire to burn him. The Ethiopic version before fire and water reads, "into the deep"; meaning either the sea or some deep pit, or off a precipice. All this is said to aggravate the case, and show the miserable condition the child was in, from the frequency of the fits, and the danger he was exposed to:

but if thou canst do any thing. This man's faith was very weak, and perhaps weaker than when he first came from home with his child. He had brought him to the disciples of Christ, and they could not cure him; the evil spirit was as strong, or stronger in him than ever; he now lay in a violent fit, and in a most miserable condition; so that he was almost ready to despair of healing: some small hopes he had that Christ might be able to relieve in this case; but he puts an if upon his power, and earnestly entreats him, if he had any, he would put it forth:

have compassion on us, and help us; his child that lay in such a deplorable condition, rolling on the ground at his feet; and himself, who was greatly afflicted for him: he tries, in very moving language, both the power and pity of Christ; and begs that if he had either, he would exert them on this occasion.
