Future of the Jews
A Sermon on Romans 11:28-32
As regards the gospel, they are enemies for your sake. But as regards election, they are beloved for the sake of their forefathers. For the gifts and the calling of God are irrevocable. For just as you were at one time disobedient to God but now have received mercy because of their disobedience, so they too have now been disobedient in order that by the mercy shown to you they also may now receive mercy. For God has consigned all to disobedience, that he may have mercy on all. (ESV)
God's way of showing mercy; God not the author of sin; but uses it for His glory; shut up to mercy; 'all Israel' cannot mean the elect; nor elect Jews only.
