He answered and said, Who is he, Lord, that I might believe on him?

People's New Testament

9:35-38 Dost thou believe on the Son of God? Jesus sought the poor excommunicated man, revealed himself to him and was confessed. The man had lost the world, but found Christ. Observe that he believes with the heart, confesses with the mouth, and shows his faith by his homage.

Wesley's Notes

9:36 Who is he, that I may believe? - This implies some degree of faith already. He was ready to receive whatever Jesus said.

Jamieson-Fausset-Brown Bible Commentary

36. He answered and said, Who is he, Lord, that I may believe on him?-"His reply is affirmative, and believing by anticipation, promising faith as soon as Jesus shall say who He is" [Stier].

Matthew Henry's Concise Commentary

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.
