"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.'"
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;
for the Lord will execute his sentence upon the earth with rigor and dispatch."
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."
What shall we say, then? That Gentiles who did not pursue righteousness have attained it, that is, righteousness through faith;
but that Israel who pursued the righteousness which is based on law did not succeed in fulfilling that law.
Why? Because they did not pursue it through faith, but as if it were based on works. They have stumbled over the stumbling stone,
as it is written, "Behold, I am laying in Zion a stone that will make men stumble, a rock that will make them fall; and he who believes in him will not be put to shame."
