All Israel Will Be Saved, for God's Gifts and His Call Are Irrevocable

The inclusion of the Gentiles is intended to provoke God's people to repentance, remembering their story and mission in the world. And if there were any doubt about that above argument, it should be put to rest after reading Paul's very next statement. Just as you who are at one time disobedient to God have now received mercy as a result of their disobedience, so they too have now become disobedient in order that they too may now receive mercy from God. So indeed, this God is out to redeem all nations. His promises, his gifts, his call are irrevocable. They're irrevocable and he has incredible ways of using our brokenness and mistakes to help bring redemption
