Who is Grace for Anyway?

Romans 11:1-2a; 29-32 (NRSV) I ask, then, has God rejected his people? By no means! I myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin. God has not rejected his people whom he foreknew. Do you not know what the scripture says of Elijah, how he pleads with God against Israel? for the gifts and the calling of God are irrevocable. Just as you were once disobedient to God but have now received mercy because of their disobedience, so also they have now been disobedient in order that, by the mercy shown to you, they also may now receive mercy. For God has imprisoned all in disobedience so that he may be merciful to all.
