Romans 9:27-29
(27) Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:
(28) For he will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth.
(29) And as Esaias said before, Except the Lord of Sabaoth had left us a seed, we had been as Sodoma, and been made like unto Gomorrha.
Here Paul quoted Old Testament verses to support the fact that God in His sovereign choice and calling always includes a Jewish segment, though it is a minority. The passages quoted (Isa. 10:22-23 and 1:9, both from the LXX) make it clear that in God’s judgment on rebellious Israel He by sovereign choice preserves and saves a remnant. Those promises were fulfilled in the Captivity and Exile of both Israel and Judah and in the destruction of Jerusalem in a.d. 70 and will also be fulfilled in the national end-time deliverance of Israel (Rom. 11:26-27). Even today the same principle is true. Jews who become members of the church, the body of Christ, are what Paul later called “a remnant chosen by grace” (11:5), which included himself (11:1).
