And—the καί suggests relation both in subject-matter, in time, place, occasion, and theme, with that which had preceded—as Jesus was passing by, going along his way, he saw a man blind from birth (cf.
ἐκ κοιλίας μητρὸς αὐτοῦ, Acts 3:2; Acts 14:8). He was obviously a well-known beggar, who had often proclaimed the fact that he was blind from birth (see John 9:8). Such a condition and history rendered the cure more difficult and hopeless in the view of ordinary professors of the healing art, and the juxtaposition of such a symbolic fact with the near activity of those who were boasting of their Abrahamic privilege and their national and mere hereditary advantages, is one of the instances of the unconscious poesy of the gospel history.
There he sits, the very type of the race which says, "We see," but which to Christ's eye was proclaiming its utter helplessness and blindness, not asking even to be illumined, and revealing the fundamental injury done to the very race and nature of man, and calling for all the healing power that he had been sent into the world to dispense.
The man who had been struck blind, or whose eyesight had been slowly dosed by disease, became the type of the effect of special sins upon the character and life; thus e.g. vanity conceals radical defects and weaknesses; pride hides from the sinner's own view his own transgressions; temporary blindness to great faults is one of the symptoms of gross sin like David's, and prejudice is proverbially blind and deaf; but here is a man who is nothing less than the type of a congenital bias to evil, of hereditary damage done to human nature.
Unless Christ can pour light upon those who are born blind, he is not the Savior the world needs.
