Romans 11:1-7, 28, 29

I ask then: Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin. God did not reject his people, whom he foreknew. Don’t you know what Scripture says in the passage about Elijah—how he appealed to God against Israel: “Lord, they have killed your prophets and torn down your altars; I am the only one left, and they are trying to kill me”? And what was God’s answer to him? “I have reserved for myself seven thousand who have not bowed the knee to Baal.” So too, at the present time there is a remnant chosen by grace. And if by grace, then it cannot be based on works; if it were, grace would no longer be grace. What then? What the people of Israel sought so earnestly they did not obtain. The elect among them did, but the others were hardened

As far as the gospel is concerned, they are enemies for your sake; but as far as election is concerned, they are loved on account of the patriarchs

for God’s gifts and his call are irrevocable.
