Romans 9:6-7 - Exposition

But it is not as though the Word of God hath taken none effect (or, hath come to naught, ἐκπεπτωκεν ). For they are not all Israel who are of Israel: neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called . The promises to the patriarchs never, from the first, implied the inheritance of them by all the physical descendants of those patriarchs; even in Israel there is a recognized distinction between being of the race of Israel and being the true Israel of God; in the original promise to Abraham the descendants of Ishmael (though equally with those of Isaac, his physical seed) were excluded. And so even the race of Israel is but a part of the whole seed of Abraham, to whom the promise was made. Hence it follows that the present exclusion of the majority of even the race of Israel from the inheritance of the promises is not inconsistent with the original purport of those promises. The quotation from Genesis 21:12 , "In Isaac," etc., is properly (as in the original Hebrew) "In Isaac shall a seed be named to thee;" i.e. "In Isaac it shall come to pass that posterity of thine shall have the name and position of the seed of Abraham, and be recognized as the inheritors of the promise" (Meyer).
