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.
26. And the spirit cried, and rent him sore, and came out of him; and he was as one dead; insomuch that many said, He is dead—The malignant, cruel spirit, now conscious that his time was come, gathers up his whole strength, with intent by a last stroke to kill his victim, and had nearly succeeded. But the Lord of life was there; the Healer of all maladies, the Friend of sinners, the Seed of the woman, "the Stronger than the strong man armed," was there. The very faith which Christ declared to be enough for everything being now found, it was not possible that the serpent should prevail. Fearfully is he permitted to bruise the heel, as in this case; but his own head shall go for it—his works shall be destroyed (1Jo 3:8).
