John 9:39 Jesus said, "For judgment I came into this world, that those who do not see may see, and those who see may become blind."
Imagine you're in a dark room
some people are leading you
they claim that they are squinting really hard, with their God given eyes they can see
Others - just admit they are blind.. can't see a thing... lost
Then there's the Light of the world.... the sun bursts into light within the room
(cf John 8 - esp v 12)
Then those who were lost finally see
those who were squinting so hard and claiming to see are now blind...
