The apostle, having made his way to that which he had to say, concerning the rejection of the body of his countrymen, with a protestation of his own affection for them and a concession of their undoubted privileges, comes in these verses, and the following part of the chapter, to prove that the rejection of the Jews, by the establishment of the gospel dispensation, did not at all invalidate the word of God's promise to the patriarchs: Not as though the word of God hath taken no effect (Rom 9:6), which, considering the present state of the Jews, which created to Paul so much heaviness and continual sorrow (Rom 9:2), might be suspected. We are not to ascribe inefficacy to any word of God: nothing that he has spoken does or can fall to the ground; see Isa 55:10, Isa 55:11. The promises and threatenings shall have their accomplishment; and, one way or other, he will magnify the law and make it honourable. This is to be understood especially of the promise of God, which by subsequent providences may be to a wavering faith very doubtful; but it is not, it cannot be, made of no effect; at the end it will speak and not lie.

Now the difficulty is to reconcile the rejection of the unbelieving Jews with the word of God's promise, and the external tokens of the divine favour, which had been conferred upon them. This he does in four ways: - 1. By explaining the true meaning and intention of the promise, Rom 9:6-13. 2. By asserting and proving the absolute sovereignty of God, in disposing of the children of men, Rom 9:14-24. 3. By showing how this rejection of the Jews, and the taking in of the Gentiles, were foretold in the Old Testament, Rom 9:25-29. 4. By fixing the true reason of the Jews' rejection, Rom 9:30, to the end.

In this paragraph the apostle explains the true meaning and intention of the promise. When we mistake the word, and misunderstand the promise, no marvel if we are ready to quarrel with God about the accomplishment; and therefore the sense of this must first be duly stated. Now he here makes it out that, when God said he would be a God to Abraham, and to his seed (which was the famous promise made unto the fathers), he did not mean it of all his seed according to the flesh, as if it were a necessary concomitant of the blood of Abraham; but that he intended it with a limitation only to such and such. And as from the beginning it was appropriated to Isaac and not to Ishmael, to Jacob and not to Esau, and yet for all this the word of God was not made of no effect; so now the same promise is appropriated to believing Jews that embrace Christ and Christianity, and, though it throws off multitudes that refuse Christ, yet the promise is not therefore defeated and invalidated, any more than it was by the typical rejection of Ishmael and Esau.

I.He lays down this proposition - that they are not all Israel who are of Israel (Rom 9:6), neither because they are, etc., Rom 9:7. Many that descended from the loins of Abraham and Jacob, and were of that people who were surnamed by the name of Israel, yet were very far from being Israelites indeed, interested in the saving benefits of the new covenant. They are not all really Israel that are so in name and profession. It does not follow that, because they are the seed of Abraham, therefore they must needs be the children of God, though they themselves fancied so, boasted much of, and built much upon, their relation to Abraham, Mat 3:9; Joh 8:38, Joh 8:39. But it does not follow. Grace does not run in the blood; nor are saving benefits inseparably annexed to external church privileges, though it is common for people thus to stretch the meaning of God's promise, to bolster themselves up in a vain hope.

II.He proves this by instances; and therein shows not only that some of Abraham's seed were chosen, and others not, but that God therein wrought according to the counsel of his own will; and not with regard to that law of commandments to which the present unbelieving Jews were so strangely wedded.

1.He specifies the case of Isaac and Ishmael, both of them the seed of Abraham; and yet Isaac only taken into covenant with God, and Ishmael rejected and cast out. For this he quotes Gen 21:12, In Isaac shall thy seed be called, which comes in there as a reason why Abraham must be willing to cast out the bond-woman and her son, because the covenant was to be established with Isaac, Gen 17:19. And yet the word which God had spoken, that he would be a God to Abraham and to his seed, did not therefore fall to the ground; for the blessings wrapt up in that great word, being communicated by God as a benefactor, he was free to determine on what head they should rest, and accordingly entailed them upon Isaac, and rejected Ishmael. This he explains further (Rom 9:8, Rom 9:9), and shows what God intended to teach us by this dispensation. (1.) That the children of the flesh, as such, by virtue of their relation to Abraham according to the flesh, are not therefore the children of God, for then Ishmael had put in a good claim. This remark comes home to the unbelieving Jews, who boasted of their relation to Abraham according to the flesh, and looked for justification in a fleshly way, by those carnal ordinances which Christ had abolished. They had confidence in the flesh, and looked for justification in a fleshly way, by those carnal ordinances which Christ had abolished. They had confidence in the flesh, Phi 3:3. Ishmael was a child of the flesh, conceived by Hagar, who was young and fresh, and likely enough to have children. There was nothing extraordinary or supernatural in his conception, as there was in Isaac's; he was born after the flesh (Gal 4:29), representing those that expect justification and salvation by their own strength and righteousness. (2.) That the children of the promise are counted for the seed. Those that have the honour and happiness of being counted for the seed have it not for the sake of any merit or desert of their own, but purely by virtue of the promise, in which God hath obliged himself of his own good pleasure to grant the promised favour. Isaac was a child of promise; this his proves, Rom 9:9, quoted from Gen 18:10. he was a child promised (so were many others), and he was also conceived and born by force and virtue of the promise, and so a proper type and figure of those who are now counted for the seed, even true believers, who are born, not of the will of the flesh, nor of the will of man, but of God - of the incorruptible seed, even the word of promise, by virtue of the special promise of a new heart: see Gal 4:28. It was through faith that Isaac was conceived, Heb 11:11. Thus were the great mysteries of salvation taught under the Old Testament, not in express words, but by significant types and dispensations of providence, which to them then were not so clear as they are to us now, when the veil is taken away, and the types are expounded by the antitypes.

2.The case of Jacob and Esau (Rom 9:10-13), which is much stronger, to show that the carnal seed of Abraham were not, as such, interested in the promise, but only such of them as God in sovereignty had appointed. There was a previous difference between Ishmael and Isaac, before Ishmael was cast out: Ishmael was the son of the bond-woman, born long before Isaac, was of a fierce and rugged disposition, and had mocked or persecuted Isaac, to all which it might be supposed God had regard when he appointed Abraham to cast him out. But, in the case of Jacob and Esau, it was neither so nor so, they were both the sons of Isaac by one mother; they were conceived hex henos - by one conception; hex henos koitou, so some copies read it. The difference was made between them by the divine counsel before they were born, or had done any good or evil. Both lay struggling alike in their mother's womb, when it was said, The elder shall serve the younger, without respect to good or bad works done or foreseen, that the purpose of God according to election might stand - that this great truth may be established, that God chooses some and refuses others as a free agent, by his own absolute and sovereign will, dispensing his favours or withholding them as he pleases. This difference that was put between Jacob and Esau he further illustrates by a quotation from Mal 1:2, Mal 1:3, where it is said, not of Jacob and Esau the person, but the Edomites and Israelites their posterity, Jacob have I loved, and Esau have I hated. The people of Israel were taken into the covenant of peculiarity, had the land of Canaan given them, were blessed with the more signal appearances of God for them in special protections, supplies, and deliverances, while the Edomites were rejected, had no temple, altar, priests, nor prophets - no such particular care taken of them nor kindness shown to them. Such a difference did God put between those two nations, that both descended from the loins of Abraham and Isaac, as at first there was a difference put between Jacob and Esau, the distinguishing heads of those two nations. So that all this choosing and refusing was typical, and intended to shadow forth some other election and rejection. (1.) Some understand it of the election and rejection of conditions or qualifications. As God chose Isaac and Jacob, and rejected Ishmael and Esau, so he might and did choose faith to be the condition of salvation and reject the works of the law. Thus Arminius understands it, De rejectis et assumptis talibus, certa qualitate notatis - Concerning such as are rejected and such as are chosen, being distinguished by appropriate qualities; so John Goodwin. But this very much strains the scripture; for the apostle speaks all along of persons, he has mercy on whom (he does not say on what kind of people) he will have mercy, besides that against this sense those two objections (Rom 9:14, Rom 9:19) do not at all arise, and his answer to them concerning God's absolute sovereignty over the children of men is not at all pertinent if no more be meant than his appointing the conditions of salvation. (2.) Others understand it of the election and rejection of particular person - some loved, and others hated, from eternity. But the apostle speaks of Jacob and Esau, not in their own persons, but as ancestors - Jacob the people, and Esau the people; nor does God condemn any, or decree so to do, merely because he will do it, without any reason taken from their own deserts. (3.) Others therefore understand it of the election and rejection of people considered complexly. His design is to justify God, and his mercy and truth, in calling the Gentiles, and taking them into the church, and into covenant with himself, while he suffered the obstinate part of the Jews to persist in unbelief, and so to unchurch themselves - thus hiding from their eyes the things that belonged to their peace. The apostle's reasoning for the explication and proof of this is, however, very applicable to, and, no doubt (as is usual in scripture) was intended for the clearing of the methods of God's grace towards particular person, for the communication of saving benefits bears some analogy to the communication of church-privileges. The choosing of Jacob the younger, and preferring him before Esau the elder (so crossing hands), were to intimate that the Jews, though the natural seed of Abraham, and the first-born of the church, should be laid aside; and the Gentiles, who were as the younger brother, should be taken in in their stead, and have the birthright and blessing. The Jews, considered as a body politic, a nation and people, knit together by the bond and cement of the ceremonial law, the temple and priesthood, the centre of their unity, had for many ages been the darlings and favourites of heaven, a kingdom of priests, a holy nation, dignified and distinguished by God's miraculous appearances among them and for them. Now that the gospel was preached, and Christian churches were planted, this national body was thereby abandoned, their church-polity dissolved; and Christian churches (and in process of time Christian nations), embodied in like manner, become their successors in the divine favour, and those special privileges and protections which were the products of that favour. To clear up the justice of God in this great dispensation is the scope of the apostle here.

Neither because they are the seed of Abraham, etc. - Nor can they conclude, because they are the natural descendants of Abraham, that therefore they are all of them, without exception, the children in whom the promise is to be fulfilled.

But, in Isaac shall thy seed be called - The promise is not confined to immediate natural descent, but may be accomplished in any part of Abraham's posterity. For Abraham had several sons besides Isaac, Gen 25:1, Gen 25:2, particularly Ishmael, who was circumcised before Isaac was born, and in whom Abraham was desirous that the promise should be fulfilled, Gen 17:18, and in him God might have fulfilled the promise, had he so pleased; and yet he said to Abraham, Gen 21:12 : Not in Ishmael, but in Isaac, shall thy seed be called.

That is, they which are the children of the flesh,.... This is an explanation of the foregoing verse, and shows, that by "the seed of" Abraham are meant, the natural seed of Abraham, who are born after the flesh, or descend from him by carnal generation:

these are not the children of God; that is, not all of them, nor any of them, on account of their being children of the flesh, or Abraham's natural seed; for adoption does not come this way; men do not commence children of God by their fleshly descent; they are not "born of blood", but of God, who are the sons of God:

but the children of the promise are counted for the seed; "children of the covenant", is a common phrase with the Jews; who reckoned themselves as such, because they were the seed of Abraham: thus in their prayers they say (e) to God,

"we are thy people, , "the children of thy covenant", the children of Abraham thy friend.''

And so they were the children of the covenant, or promise, which God made with Abraham and his natural seed, respecting the land of Canaan, and their enjoyment of temporal good things in it; but they were not all of them the children of the promise, which God made to Abraham and his spiritual seed, whether Jews or Gentiles, respecting spiritual and eternal things; to whom alone the promises of God, being their God in a spiritual sense, of spiritual and eternal salvation by Christ, and of the grace of the Spirit of God, and of eternal life belong; and who are the seed which were promised to Abraham by God, saying, "thou shalt be a father of many nations", Gen 17:4, for which reasons, because these spiritual promises belong to them, and because they themselves were promised to Abraham, as his children, therefore they are called "children of the promise": or rather, because as Isaac was a child of promise, being born after the Spirit, by virtue of the promise of God, through his divine power and goodness, when there were no ground or foundation in nature, for Abraham and Sarah to hope for a son; so these are called "children of promise", Gal 4:28, because they are born again, not through the power of nature, and strength of their own free will; they are not born of the will of the flesh, nor of the will of man, but of God, according to the will of God and his abundant mercy, by the word of truth, through his power, Spirit, and grace; and by faith receive the promises made unto them; and are counted and reckoned as "Abraham's seed, and heirs according to the promise", Gal 3:29, whether they be Jews, or whether they be Gentiles: and since now the promises of God are all made good to these persons, the word of God is not without effect, or is not made void, by the casting off the children of the flesh, or the carnal seed of Abraham, who were not children of the promise in the sense now given.

Neither, because they are the seed of Abraham, are they all children--"Not in the line of mere fleshly descent from Abraham does the election run; else Ishmael, Hagar's child, and even Keturah's children, would be included, which they were not."

but--the true election are such of Abraham's seed as God unconditionally chooses, as exemplified in that promise.

in Isaac shall thy seed be called-- (Gen 21:12).
