(36) Who is he, Lord, that I might believe on him?--For "Lord" it would be better to read Sir, as in John 4:11; John 4:19; John 5:7, et. al. The man does not express by it more than the reverence to a prophet or teacher. He recognises Him by the voice which he had heard before, and now for the first time sees Him. He is ready to believe on the Messiah whom all expected, and he feels that this prophet, who had opened his eyes, can tell him who the Messiah is. The form of the question, "Who is He?" suggests that he half expected that He, upon whom he looked, was more than a prophet, and was none other than the Messiah Himself. In the absence of any such thought, the question would have taken a vague form, such as "Where is He?" or "When shall He appear?" He asks as one who knows that the object of his faith is at hand.

Verse 36. - He answered and said, And who is he, that (ἵνα) I may believe on him? The conjunction adds much to the eagerness of the reply. His faith was ready for full expression. He half suspected, as the Samaritan woman (John 4:25) did, that Jesus was pointing to himself. The τίς; rather than τί; ("who?" rather than "what?") shows the intensity of the man's desire to find and hail and trust "the Son of God." The disposition, the posture, of his mind is that of faith. The adequate object for that faith has not been revealed to him. Apt symbol of many in their passage from darkness to light. When receptive, susceptible, conscious of need, with some notion, though an obscure one, of whom and of what they most of all need, many are disposed even now to utter the same importunate request.

9:35-38 Christ owns those who own him and his truth and ways. There is particular notice taken of such a suffer in the cause of Christ, and for the testimony of a good conscience. Our Lord Jesus graciously reveals himself to the man. Now he was made sensible what an unspeakable mercy it was, to be cured of his blindness, that he might see the Son of God. None but God is to be worshipped; so that in worshipping Jesus, he owned him to be God. All who believe in him, will worship him.He answered and said,.... That is, "he that was healed", as the Syriac version reads:

who is the Lord that I might believe in him? which shows, that though he knew there was a Messiah expected, and he believed in him as to come, yet he knew not that he was already come, nor the particular person in human nature, who was the Messiah, and the Son of God; even though he had been cured of his blindness by him, and had vindicated him, and pleaded for him before the sanhedrim, and had also suffered for him; which makes it appear, that Christ does many and great things for his people before they know him: nor does their interest in him, in his favour, and in the blessings of his grace, depend upon their knowledge of him, and faith in him; as likewise, that a man may plead for Christ, and suffer much for him, and yet be ignorant of him: however, there were in this man desires of knowing Christ; he was not like those in Job 21:14; and there was a readiness in him to believe on him, as soon as he was pointed out to him; not that there is any natural disposition in men to believe, or any readiness in themselves to it, or that it is of themselves; nothing of this nature was in this man; but he having, by the power and grace of Christ, the principle of faith implanted in his heart, what he wanted was to be directed to the proper object of it, as he is in John 9:37.
