Romans 11:25

For I would not . . . that ye should be ignorant of this mystery--The word "mystery," so often used by our apostle, does not mean (as with us) something incomprehensible, but "something before kept secret, either wholly or for the most part, and now only fully disclosed" (compare Rom 16:25; Co1 2:7-10; Eph 1:9-10; Eph 3:3-6, Eph 3:9-10). lest ye should be wise in your own conceits--as if ye alone were in all time coming to be the family of God. that blindness--"hardness" in part is happened to--"hath come upon" Israel--that is, hath come partially, or upon a portion of Israel. until the fulness of the Gentiles be--"have" come in--that is, not the general conversion of the world to Christ, as many take it; for this would seem to contradict the latter part of this chapter, and throw the national recovery of Israel too far into the future: besides, in Rom 11:15, the apostle seems to speak of the receiving of Israel, not as following, but as contributing largely to bring about the general conversion of the world--but, "until the Gentiles have had their full time of the visible Church all to themselves while the Jews are out, which the Jews had till the Gentiles were brought in." (See Luk 21:24).

The apostle, having reconciled that great truth of the rejection of the Jews with the promise made unto the fathers, is, in this chapter, further labouring to mollify the harshness of it, and to reconcile it to the divine goodness in general. It might be said, "Hath God then cast away his people?" The apostles therefore sets himself, in this chapter, to make a reply to this objection, and that two ways: - I. He shows at large what the mercy is that is mixed with this wrath (v. 1-32). II. He infers thence the infinite wisdom and sovereignty of God, with the adoration of which he concludes this chapter and subject (Rom 11:33-36).

11:25 Paul usually uses the word mystery to refer to an event of the last days that has already been determined by God. Such a mystery already exists in heaven and is revealed to God’s people in the Christian era (see 16:25; 1 Cor 2:1, 7; 4:1; 15:51; Eph 1:9; 3:3, 4, 9; 6:19; Col 1:26, 27; 2:2; 4:3; 1 Tim 3:9, 16). Here, the mystery is the relationship of Jews and Gentiles in the plan of salvation, which is at the heart of this entire passage (Rom 11:11-32).
