Day and night

The narrative is breathtaking if you think about it.  Jesus passes a blind man; the presence of this blind man invokes a theological discussion with Jesus and his disciples over sin; Jesus rapidly moves through the issue of local culpability (the man or his parents), dismisses it; then in a sudden, startling, revealing burst of truth declares that this situation, this confluence of circumstances is intended for the purpose of making "manifest" the "works of God!"  It does not stop there, but continues with the charged and urgent declaration of the significance of time:

"I must work the works of him that sent me, while it is day: the night cometh, when no man can work." (John 9:4)

And then - he cures the blind man!
