Thou hast both seen him. By these words of Christ the blind man could not be carried higher than to a very small and cold portion of faith. For Christ does not mention his power, or the reason why he was sent by the Father, or what he has brought to men. But what principally belongs to faith is, to know that, by the sacrifice of his death, atonement has been made for our sins, and we are reconciled to God; that his resurrection was a triumph over vanquished death; that we are renewed by his Spirit, in order that, being dead to the flesh and to sin, we may live to righteousness; that he is the only Mediator; that the Spirit is the earnest of our adoption; in short, that in him is found every thing that belongs to eternal life. But the Evangelist either does not relate the whole of the conversation which Christ held with him, or he only means that the blind man professed his attachment to Christ, so that henceforth he began to be one of his disciples. For my own part, I have no doubt that Jesus intended to be acknowledged by him as the Christ, that from this beginning of faith he might afterwards lead him forward to a more intimate knowledge of himself.

And Jesus said unto him,.... Giving him the tokens by which he might know him: thou hast both seen him; not that he had seen him before now, with his bodily eyes; for he was blind when Christ anointed him, and sent him to Siloam to wash; nor when he came back, since Jesus was gone, and he knew not where he was; but he had seen him, that is, he had perceived and felt the power of him in restoring him to sight; and now he had seen him bodily, and did at this present time: but as this was not sufficient to distinguish him from other persons in company, he adds,
and it is he that talketh with thee; in like manner he made himself known to the woman of Samaria, John 4:26.

Jesus said unto him, Thou hast both seen him--the new sense of sight having at that moment its highest exercise, in gazing upon "the Light of the world."

Lord, I believe - What an excellent spirit was this man of! Of so deep and strong an understanding; (as he had just shown to the confusion of the Pharisees,) and yet of so teachable a temper!
