(1.) The miracle of them. They were wrought in such a manner, as plainly spake them to be the immediate products of a divine and supernatural power, and they were God's seal to his commission. Nature could not do these things, it was the God of nature; the cures were many, of diseases incurable by the art of the physician, of persons that were strangers, of all ages and conditions; the cures were wrought openly, before many witnesses, in mixed companies of persons that would have denied the matter of fact, if they could have had any colour for so doing; no cure ever failed, or was afterwards called in question; they were wrought speedily, and not (as cures by natural causes) gradually; they were perfect cures, and wrought with a word's speaking; all which proves him a Teacher come from God, for, otherwise, none could have done the works that he did, John iii. 2. He appeals to these as credentials, ch. xi. 4, 5; John v. 36. It was expected that the Messiah should work miracles (John vii. 31); miracles of this nature (Isa. xxxv. 5, 6); and we have this indisputable proof of his being the Messiah; never was there any man that did thus; and therefore his healing and his preaching generally went together, for the former confirmed the latter; thus here he began to do and to teach, Acts i. 1.
(2.) The mercy of them. The miracles that Moses wrought, to prove his mission, were most of them plagues and judgments, to intimate the terror of that dispensation, though from God; but the miracles that Christ wrought, were most of them cures, and all of them (except the cursing of the barren fig tree) blessings and favours; for the gospel dispensation is founded, and built up in love, and grace, and sweetness; and the management is such as tends not to affright but to allure us to obedience. Christ designed by his cures to win upon people, and to ingratiate himself and his doctrine into their minds, and so to draw them with the bands of love, Hos. xi. 4. The miracle of them proved his doctrine a faithful saying, and convinced men's judgments; the mercy of them proved it worthy of all acceptation, and wrought upon their affections. They were not only great works, but good works, that he showed them from his Father (John x. 32); and this goodness was intended to lead men to repentance (Rom. ii. 4), as also to show that kindness, and beneficence, and doing good to all, to the utmost of our power and opportunity, are essential branches of that holy religion which Christ came into the world to establish.
(3.) The mystery of them. Christ, by curing bodily diseases, intended to show, that his great errand into the world was to cure spiritual maladies. He is the Sun of righteousness, that arises with this healing under his wings. As the Converter of sinners, he is the Physician of souls, and has taught us to call him so, ch. ix. 12, 13. Sin is the sickness, disease, and torment of the soul; Christ came to take away sin, and so to heal these. And the particular stories of the cures Christ wrought, may not only be applied spiritually, by way of allusion and illustration, but, I believe, are very much intended to reveal to us spiritual things, and to set before us the way and method of Christ's dealing with souls, in their conversion and sanctification; and those cures are recorded, that were most significant and instructive this way; and they are therefore so to be explained and improved, to the honour and praise of that glorious Redeemer, who forgiveth all our iniquities, and so healeth all our diseases.
