John 9: 1-41
I Am the Light of the World
The man who was born blind meets Jesus twice. In the first encounter, he does not speak to Jesus. Later, when asked, he knows his healer only by the human name "Jesus." The second time he meets Jesus, he already professes his faith, and addresses him as "Lord."
The disciples themselves, speaking only once in the whole episode know Jesus only as a rabbi (v. 2). They still have some "seeing" to do in order to recognize the full identity of Jesus.
The Pharisees, on the contrary, never speak with Jesus. The irony is that they interrogate the man about Jesus. They summon his parents and question them. Yet, not even once do they ask Jesus, the target of their questioning.
Consequently, at first, some of the Pharisees still acknowledge something miraculous about what Jesus has done in saying, "How can a sinful man do such signs?"
Yet, without an encounter with Jesus, they fail to see the light. By the end, they all denounce Jesus as a sinner (v. 24) and reject any possibility of Divine power in what he has done.
One cannot see unless one comes to "the Light of the world."
