Romans 9:27-30

And concerning Israel, Isaiah the prophet cried out, “Though the people of Israel are as numerous as the sand of the seashore, only a remnant will be saved. For the LORD will carry out his sentence upon the earth quickly and with finality.” And Isaiah said the same thing in another place: “If the LORD of Heaven’s Armies had not spared a few of our children, we would have been wiped out like Sodom, destroyed like Gomorrah.” What does all this mean? Even though the Gentiles were not trying to follow God’s standards, they were made right with God. And it was by faith that this took place.
