Isaiah also cries concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:

Paul says this because Isaiah was crying out for those who would believe in Christ. It is these who are the true Israel…. The others have gone away from the law because they have not believed in him whom the law promised would alone be sufficient for salvation. Therefore they became apostate, because by not accepting Christ they became lawbreakers. Therefore, of that great number only those who God foreknew would believe have been saved. Commentary on Paul’s Epistles.
