Epheser 3:18

May be able--even still further. Greek, "May be fully able." breadth . . . length . . . depth . . . height--namely, the full dimensions of the spiritual temple, answering to "the fulness of God" (Eph 3:19), to which the Church, according to its capacity, ought to correspond (compare Eph 4:10, Eph 4:13) as to "the fulness of Christ." The "breadth" implies Christ's world-wide love, embracing all men: the "length," its being extended through all ages (Eph 3:21); the "depth," its profound wisdom which no creature can fathom (Rom 11:33); the "height," its being beyond the reach of any foe to deprive us of (Eph 4:8) [BENGEL]. I prefer to understand "the breadth," &c., to refer to the whole of the vast mystery of free salvation in Christ for all, Gentile and Jew alike, of which Paul had been speaking (Eph 3:3-9), and of which he now prays they may have a fuller comprehension. As subsidiary to this, and the most essential part of it, he adds, "and to know the love of Christ" (Eph 3:19). GROTIUS understands depth and height of God's goodness raising us from the lowest depression to the greatest height.

This chapter consists of two parts. I. Of the account which Paul gives the Ephesians concerning himself, as he was appointed by God to be the apostle of the Gentiles (Eph 3:1-13). II. Of his devout and affectionate prayer to God for the Ephesians (Eph 3:14-21). We may observe it to have been very much the practice of this apostle to intermix, with his instructions and counsels, intercessions and prayers to God for those to whom he wrote, as knowing that all his instructions and teachings would be useless and vain, except God did co-operate with them, and render them effectual. This is an example that all the ministers of Christ should copy after, praying earnestly that the efficacious operations of the divine Spirit may attend their ministrations, and crown them with success.

3:18 how wide, how long, how high, and how deep his love is: Christ’s love is great in every dimension (cp. Rom 8:38-39).
