(Rom 9:6) “Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: (7) Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.” We have before us a key instructional tool of God: a physical truth to explain a spiritual. From the very beginning He made these physical separations, knowing that when the spiritual is revealed, they would be used in instruction.
