I say then, Has God cast away his people? God forbid. For I also am an Israelite, of the descendants of Abraham, of the tribe of Benjamin.

Since Paul has shown that the people of Israel did not believe, now, in order that it should not be thought that he has said that they were all unbelievers, he shows that God has not rejected the inheritance which he promised to the descendants of Abraham. For he would not have promised them a kingdom if he knew that none of them would believe…. By using himself as an example, he shows that the part of Israel which God foreknew would be saved had in fact been saved and that the part which had been consigned to perdition because of its constant unbelief might yet be saved.
