Romans 11:25-29 AMPC
Lest you be self-opinionated (wise in your own conceits), I do not want you to miss this hidden truth and mystery, brethren: a hardening (insensibility) has [temporarily] befallen a part of Israel [to last] until the full number of the ingathering of the Gentiles has come in,
And so all Israel will be saved. As it is written, The Deliverer will come from Zion, He will banish ungodliness from Jacob. [Isa. 59:20, 21.]
And this will be My covenant (My agreement) with them when I shall take away their sins. [Isa. 27:9; Jer. 31:33.]
From the point of view of the Gospel (good news), they [the Jews, at present] are enemies [of God], which is for your advantage and benefit. But from the point of view of God's choice (of election, of divine selection), they are still the beloved (dear to Him) for the sake of their forefathers.
For God's gifts and His call are irrevocable. [He never withdraws them when once they are given, and He does not change His mind about those to whom He gives His grace or to whom He sends His call.]
