Romans 11:29

27For this is my covenant unto them, when I shall take away their sins.

28As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the father’s sakes.

29For the gifts and calling of God are without repentance.

30For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:

31Even so have these also now not believed, that through your mercy they also may obtain mercy.
