9:11 (For [the children] being not yet born, neither having done any good or evil, that the {m} purpose of God according to election might {8} stand, not of works, but of him that calleth;)
(m) God's decree which proceeds from only his good will, by which it pleases him to choose one, and refuse the other.
(8) Paul does not say, might be made, but being made might remain. Therefore they are deceived who make foreseen faith the cause of election, and foreknown infidelity the cause of reprobation.
9:11 For [the children]. The children, yet unborn, were both Isaac's seed according to the flesh; hence, according to the flesh, of the promised seed, and both equally without works, neither having done good nor evil.
That the purpose of God according to election might stand. That it might stand forth that he made the choice of his own will, freely. Of his own will he chose Jacob, yet unborn, to become the head of the chosen race, rather than Esau. Note that this election was not to eternal salvation, but to become the head of a people. As Moses, Samuel, and John the Baptist were raised up for a great work of God, so was Jacob.
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.
