John 9
The man born blind (the sixth sign) becomes the instrument through which Jesus enacts his declaration "I am the light of the world," and whose progressive confession mirrors the Gospel's own growing clarification of Jesus' identity. When the disciples ask whether his blindness resulted from his sin or his parents', Jesus reframes the question: this happened so that the works of God might be displayed in him, and he anoints the blind man's eyes with spittle and mud—a sacramental touch reminiscent of creation and covenant. The man's journey to sight parallels a deepening faith: first he describes Jesus as "a man called Jesus," then recognizes him as a prophet, then acknowledges him as from God (para theou), and finally confesses "Lord, I believe" when Jesus reveals himself as the Son of Man—a progression from sensory experience through reasonable inference to committed faith. The Pharisees' interrogation grows increasingly hostile, expelling the man from the synagogue when he insists that Jesus is from God, yet unable to explain how a sinner could perform such signs. Jesus returns to pronounce a final judgment: "For judgment I have come into this world, so that those who are blind may see and those who see may become blind," revealing that the willful refusal to accept Jesus as the light results in deeper spiritual darkness. The chapter thus inverts the categories of sight and blindness: the physically blind man sees and believes, while the spiritually sighted Pharisees choose darkness and become blind.
John 9:41
Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore your sin remaineth — Jesus's response reveals the paradox of the Pharisees' condition: if they were truly blind (ignorant), they would have no responsibility for sin. But they claim to see ('we see'), to have knowledge, understanding, and authority. Their sin is not ignorance but willful refusal of truth—the claim to see while rejecting the light. 'Therefore your sin remaineth'—their sin is not forgiven because it is not acknowledged. They stand in judgment: convicted by their own claim to knowledge, they are bound by their refusal of truth. The Gospel ends on this note of tragic judgment: those who see themselves as sighted are actually blind; those who acknowledge blindness receive sight.
John 9:38
And he said, Lord, I believe. And he worshipped him — the man's response is faith ('I believe') and worship ('he worshipped him,' prosekynēsen autōi). His journey from 'a man called Jesus' to 'prophet' to 'one whom God hears' culminates in recognition of Jesus as the Son of God and worship. Worship (proskuneō) is the response due to God and to God's representative. The man's faith is complete, and it is expressed in adoration.
John 9:39
And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind — Jesus states the paradoxical purpose of his coming: judgment. Those who are spiritually blind ('see not') will receive sight through faith; those who claim to see (the authorities who trust in their own understanding) will be made blind. This reversal is the judgment: the world's values are overturned. The supposedly blind beggar sees and believes; the supposedly learned authorities remain blind to the truth.
