I am always struck by verse 2
"Neither this man nor his parents sinned," said Jesus, "but this [blindness] happened so that the work of God might be displayed in his life.
And then by verse 39
Jesus said, "For judgment I have come into this world, so that the blind will see and those who see will become blind."
So are we blind or do we see?
I would say we are blind; we turn our eyes from things we choose not to change, we think we see but we have a narrow window. It is only through Christ in our life and eyes that we truly see and are moved to action.
