2 Corinthians 11:2

For I am jealous--The justification of his self-commendations lies in his zealous care lest they should fall from Christ, to whom he, as "the friend of the Bridegroom" (Joh 3:29), has espoused them; in order to lead them back from the false apostles to Christ, he is obliged to boast as an apostle of Christ, in a way which, but for the motive, would be "folly." godly jealousy--literally, "jealousy of God" (compare Co2 1:12, "godly sincerity," literally, "sincerity of God"). "If I am immoderate, I am immoderate to God" [BENGEL]. A jealousy which has God's honor at heart (Kg1 19:10). I . . . espoused you--Paul uses a Greek term applied properly to the bridegroom, just as he ascribes to himself "jealousy," a feeling properly belonging to the husband; so entirely does he identify himself with Christ. present you as a chaste virgin to Christ--at His coming, when the heavenly marriage shall take place (Mat 25:6; Rev 19:7, Rev 19:9). What Paul here says he desires to do, namely, "present" the Church as "a chaste virgin" to Christ, Christ Himself is said to do in the fuller sense. Whatever ministers do effectively, is really done by Christ (Eph 5:27-32). The espousals are going on now. He does not say "chaste virgins"; for not individual members, but the whole body of believers conjointly constitute the Bride.
