25 As indeed he says in Hose'a, "Those who were not my people I will call 'my people,' and her who was not beloved I will call 'my beloved.'" 26 "And in the very place where it was said to them, 'You are not my people,' they will be called 'sons of the living God.'" 27 And Isaiah cries out concerning Israel: "Though the number of the sons of Israel be as the sand of the sea, only a remnant of them will be saved; 28 for the Lord will execute his sentence upon the earth with rigor and dispatch." 29 And as Isaiah predicted, "If the Lord of hosts had not left us children, we would have fared like Sodom and been made like Gomor'rah."

Commentary on Romans 9:25-29
(Read Romans 9:25-29)
The rejecting of the Jews, and the taking in the Gentiles, were foretold in the Old Testament. It tends very much to the clearing of a truth, to observe how the Scripture is fulfilled in it. It is a wonder of Divine power and mercy that there are any saved: for even those left to be a seed, if God had dealt with them according to their sins, had perished with the rest. This great truth this Scripture teaches us. Even among the vast number of professing Christians it is to be feared that only a remnant will be saved.
