What does John 9:34-38 mean?

34 They answered and said unto him, Thou wast altogether born in sins, and dost thou teach us? And they cast him out. 35 Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? 36 He answered and said, Who is he, Lord, that I might believe on him? 37 And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. 38 And he said, Lord, I believe. And he worshipped him. (John 9:34-38 KJV)

William Burkitt’s Commentary

Observe here, 1. A special instance of Pharisaical pride; they account this poor man a vile person, whom heaven had marked by his native blindness for some extraordinary wickedness. How prone are we to judge them the greatest sinners, whom we observe to be the greatest sufferers!

Observe, 2. From reviling they proceed to excommunicating; They cast him out; that is, out of the communion of the Jewish church. O happy man! who having lost a synagogue, has found heaven! Behold this blind man, and admire him for a resolute confessor, stoutly defending the gracious author of his cure, against the cavils of the Pharisees, and maintaining the innocence and honour of so blessed a benefactor.

Observe, 3. Our Saviour’s regard to this blind man, whom the Pharisees had set at nought and excommunicated: He finds him out, reveals himself more fully to him, and directs him to believe in him.

Where observe, That the miracle which Christ had wrought upon the blind man, did not convert him, and work faith in him, till Christ revealed himself unto him, and enabled him to discern the truth of what he revealed.

Learn hence, That miracles confirm faith, but miracles alone can work faith. The blind man had experienced a miracle wrought upon him, yet remains an unbeliever, till Christ said, I am he.

Observe, 4. How readily the man receives the Lord Jesus Christ by faith, upon the fore-mentioned revelation of himself unto him: he instantly said, Lord, I believe; and in testimony thereof, worships him; that is, as God incarnate, as God manifested in the flesh.

Thence learn, That true knowledge of the Son of God will beget faith in him: and true faith in him will be productive of homage and adoration, of obedience and subjection to him. He that knows Christ aright, will believe, and he that believes, will worship and obey: He said, Lord, I believe. And he worshipped him.
