Amir Tsarfati - This is the Mystery of the Blindness

Concerning the gospel they are enemies for your sake, but concerning the election they are beloved for the sake of the fathers. For the gifts and the calling of God are irrevocable. For as you were once disobedient to God, yet have now obtained mercy through their disobedience, even so these also have now been disobedient, that through the mercy shown you they also may obtain mercy. For God has committed them all to disobedience, that He might have mercy on all. – Romans 11:28-32
