6. Not as though the word of God had taken none effect--"hath fallen to the ground," that is, failed: compare Lu 16:17, Greek.
      for they are not all Israel which are of Israel--better, "for not all they which are of Israel are Israel." Here the apostle enters upon the profound subject of ELECTION, the treatment of which extends to the end of the eleventh chapter--"Think not that I mourn over the total loss of Israel; for that would involve the failure of God's word to Abraham; but not all that belong to the natural seed, and go under the name of 'Israel,' are the Israel of God's irrevocable choice." The difficulties which encompass this subject lie not in the apostle's teaching, which is plain enough, but in the truths themselves, the evidence for which, taken by themselves, is overwhelming, but whose perfect harmony is beyond human comprehension in the present state. The great source of error here lies in hastily inferring (as THOLUCK and others), from the apostle's taking tip, at the close of this chapter, the calling of the Gentiles in connection with the rejection of Israel, and continuing this subject through the two next chapters, that the Election treated of in the body of this chapter is national, not personal Election, and consequently is Election merely to religious advantages, not to eternal salvation. In that case, the argument of Ro 9:6, with which the subject of Election opens, would be this: "The choice of Abraham and his seed has not failed; because though Israel has been rejected, the Gentiles have taken their place; and God has a right to choose what nation He will to the privileges of His visible kingdom." But so far from this, the Gentiles are not so much as mentioned at all till towards the close of the chapter; and the argument of this verse is, that "all Israel is not rejected, but only a portion of it, the remainder being the 'Israel' whom God has chosen in the exercise of His sovereign right." And that this is a choice not to mere external privileges, but to eternal salvation, will abundantly appear from what follows.
