Romans 11:1-7, 28-29

I say then, has God rejected and disowned His people? Certainly not! For I too am an Israelite, a descendant of Abraham, of the tribe of Benjamin. [1 Sam 12:22; Jer 31:37; 33:24-26; Phil 3:5] God has not rejected His [chosen] people whom He foreknew. Or do you not know what the Scripture says of Elijah, how he pleads with God against Israel? [Ps 94:14; 1 Kin 19] “Lord, THEY HAVE KILLED YOUR PROPHETS, THEY HAVE TORN DOWN YOUR ALTARS, AND I ALONE AM LEFT [of the prophets], AND THEY ARE SEEKING MY LIFE.” But what is God’s response to him? “I HAVE KEPT for Myself SEVEN THOUSAND MEN WHO HAVE NOT BOWED THE KNEE TO BAAL.” [1 Kin 19:18] So too then, at the present time there has come to be a remnant [a small believing minority] according to God’s gracious choice. But if it is by grace [God’s unmerited favor], it is no longer on the basis of works, otherwise grace is no longer grace [it would not be a gift but a reward for works]. What then? Israel failed to obtain what it was seeking [that is, God’s favor by obedience to the Law], but the elect [those chosen few] obtained it, while the rest of them became hardened and callously indifferent

From the standpoint of the gospel, the Jews [at present] are enemies [of God] for your sake [which is for your benefit], but from the standpoint of God’s choice [of the Jews as His people], they are still loved by Him for the sake of the fathers. For the gifts and the calling of God are irrevocable [for He does not withdraw what He has given, nor does He change His mind about those to whom He gives His grace or to whom He sends His call].
