In the words of theologian and commentator Charles Hodge (1797-1878),
“They [meaning, the people of Israel] stand now, therefore, and ever have stood, in a relation to God which no other nation ever has sustained; and, in consequence of this relation, their restoration to the divine favour is an event in itself probable, and one, which Paul afterwards teaches (ver. 25-26) God has determined to accomplish.”
God will finish what He started, which is why the Jewish people have been preserved throughout history (against all odds) and why they are back in the Land as a nation (against even greater odds).
His purposes will stand, and no one can overrule His hand.
Is God finished with Israel as a nation? God forbid!...
