It needs to be emphasized that the rejection of this interpretation is not dictated by a predestinarian interest. Even if it were granted that "foreknew" means the foresight of faith, the biblical doctrine of sovereign election is not thereby eliminated or disproven. For it is certainly true that God foresees faith; he foresees all that comes to pass. The question would then simply be: whence proceeds this faith which God foresees? And the only biblical answer is that the faith which God foresees is the faith he himself creates (cf. John 3:3-8; 6:44,45,65; Ephesians 2:8; Philippians 1:29; 2 Peter 1:2). Hence his eternal foresight of faith is preconditioned by his decree to generate this faith in those whom he foresees as believing, and we are thrown back upon the differentiation which proceeds from God's own eternal and sovereign election to faith and its consequents. The interest, therefore, is simply one of interpretation as it should be applied to this passage. On exegetical grounds we shall have to reject the view that "foreknew" refers to the foresight of faith....
.... "foreknow merely adds the thought of "beforehand" to the word "know". Many times in Scripture "know" has a pregnant meaning which goes beyond that of mere cognition. It is used ina sense practically synonymous with "love", to set regard upon, to know with peculiar interest, delight, affection, and action (cf Gen. 18:19; Exod. 2:25; Psalm 1:6; 144:3; Jer. 1:5; Amos 3:2; Hosea 13:5; Matt. 7:23; 1 Cor. 8:3; Gal. 4:9; 2 Tim. 2:19; 1 John 3:1). There is no reason why this import of the word "know" should not be applied to "foreknow" in this passage, as also in 11:2 where it also occurs in the same kind of construction and where the thought of election is patently present. (cf 11:5,6).... It means "whom he set regard upon" or "whom he knew from eternity with distinguishing affection and delight" and is virtually equivalent to "whom he foreloved". This interpretation, furthermore, is in agreement with the efficient and determining action which is so conspicuous in every other link of the chain—it is God who predestinates, it is God who calls, it is God who justifies, and it is he who glorifies. FOresight of faith would be out of accord with the determinative action which is predicated of God in these other instances and would constitute a weakening of the total emphasis at the point where we should least expect it... It is not the foresight of difference but the foreknowledge that makes difference to exist, not a foresight that recognizes existence but the foreknowledge that determines existence. It is sovereign distinguishing love.
