Jesus heard that they had cast him out,.... this being perhaps the first instance, of putting in execution the act they had made, Joh 9:22, and was a stretching of that act; which only threatened with an ejection, in case any should confess Jesus to be the Messiah; which this man had not done as yet, only had said he was a prophet, and that he was of God; it made a very great noise in the city, and the report of it was soon spread over it; and it became the talk of everyone, and so Jesus, as man, came to hear of it; though he, as God, knew it the very instant it was done, and needed not any to make report of it to him:and when he had found him: not by chance, meeting him at an unawares, but seeking him; and knowing where he was, went to the very place, and found him in this piteous condition, abandoned by all mankind: this is an emblem of Christ's seeking after his chosen ones, both in redemption, and in the effectual calling, who are like sheep going astray, and never come to, and lay hold on Christ, till he comes first, seeks after, and apprehends them: he sends his ministers and his Gospel after them, where they are, and his Spirit into their hearts; yea, he comes himself, and enters there, and dwells in them by faith: he knows where they are, as he did Matthew the publican, Zacchaeus, and the woman of Samaria; and even though they are at the ends of the earth; and he goes and looks them up, and finds them; and he finds them in a deplorable condition, in a desert, in a waste howling wilderness, hopeless and helpless, poor and miserable, and blind and naked; in a pit wherein is no water; in the mire and clay of sin; in the paw of Satan, and under the power of darkness.
He said unto him, dost thou believe on the Son of God? the Persic version adds, "who hath healed thee": this supposes that there was a Son of God, or a divine person known by the Jews under this character, and that the expected Messiah would appear as such; and that, as such, he is the object of faith, and therefore, as such, must be God, since a creature, though ever so much dignified, or with whatsoever office invested, is not the object of faith, trust, and confidence, with respect to everlasting life and happiness: and it may be observed, that whenever Christ finds any of his people, he brings them to believe in him as the Son of God for righteousness and life: he himself is the author of faith in them, as well as the object of it; and no doubt power went along with these words, creating faith in this man: this was a most proper and pertinent question put to him in his present case, and suggests, that if he believed in the Son of God, it was no matter in what situation he was among men: since he would then appear to be a Son of God himself by adopting grace, and so an heir of God, and a joint heir with Christ; would receive the remission of his sins, openly justified in the court of conscience, as well of God, and be everlastingly saved: and this question is put by Christ, not as though he was ignorant, whether he believed in him or not; for he knew from the beginning, who would, and who would not believe in him: he that knew whether Peter loved him or not, knew whether this man believed in him or not; but this he said to draw forth the principle of faith, which was wrought in him, into act and exercise, and to direct it to its proper object.
