Jesus answered, “The light will be with you for only a little longer. Walk in the light while you can. Then you won't be caught walking blindly in the dark.
“The Lord has blinded the eyes of the people, and he has made the people stubborn. He did this so that they could not see or understand, and so that they would not turn to the Lord and be healed.”
The people were stubborn, and something still keeps them from seeing the truth when the Law is read. Only Christ can take away the covering that keeps them from seeing.
The god who rules this world has blinded the minds of unbelievers. They cannot see the light, which is the good news about our glorious Christ, who shows what God is like.
We used to be stupid, disobedient, and foolish, as well as slaves of all sorts of desires and pleasures. We were evil and jealous. Everyone hated us, and we hated everyone.
You claim to be rich and successful and to have everything you need. But you don't know how badly off you are. You are pitiful, poor, blind, and naked.
