6 But [it is] not as though the word of God hath come to nought. For they are not all Israel, that are of Israel: 7 neither, because they are Abraham's seed, are they all children: but, In Isaac shall thy seed be called. 8 That is, it is not the children of the flesh that are children of God; but the children of the promise are reckoned for a seed. 9 For this is a word of promise, According to this season will I come, and Sarah shall have a son. 10 And not only so; but Rebecca also having conceived by one, [even] by our father Isaac— 11 for [the children] being not yet born, neither having done anything good or bad, that the purpose of God according to election might stand, not of works, but of him that calleth, 12 it was said unto her, The elder shall serve the younger. 13 Even as it is written, Jacob I loved, but Esau I hated.

Commentary on Romans 9:6-13
(Read Romans 9:6-13)
The rejection of the Jews by the gospel dispensation, did not break God's promise to the patriarchs. The promises and threatenings shall be fulfilled. Grace does not run in the blood; nor are saving benefits always found with outward church privileges. Not only some of Abraham's seed were chosen, and others not, but God therein wrought according to the counsel of his own will. God foresaw both Esau and Jacob as born in sin, by nature children of wrath even as others. If left to themselves they would have continued in sin through life; but for wise and holy reasons, not made known to us, he purposed to change Jacob's heart, and to leave Esau to his perverseness. This instance of Esau and Jacob throws light upon the Divine conduct to the fallen race of man. The whole Scripture shows the difference between the professed Christian and the real believer. Outward privileges are bestowed on many who are not the children of God. There is, however, full encouragement to diligent use of the means of grace which God has appointed.
