3:13-19 The apostle seems to be more anxious lest the believers should be discouraged and faint upon his tribulations, than for what he himself had to bear. He asks for spiritual blessings, which are the best blessings. Strength from the Spirit of God in the inner man; strength in the soul; the strength of faith, to serve God, and to do our duty. If the law of Christ is written in our hearts, and the love of Christ is shed abroad there, then Christ dwells there. Where his Spirit dwells, there he dwells. We should desire that good affections may be fixed in us. And how desirable to have a fixed sense of the love of God in Christ to our souls! How powerfully the apostle speaks of the love of Christ! The breadth shows its extent to all nations and ranks; the length, that it continues from everlasting to everlasting; the depth, its saving those who are sunk into the depths of sin and misery; the height, its raising them up to heavenly happiness and glory. Those who receive grace for grace from Christ's fulness, may be said to be filled with the fulness of God. Should not this satisfy man? Must he needs fill himself with a thousand trifles, fancying thereby to complete his happiness?

19. passeth—surpasseth, exceeds. The paradox "to know … which passeth knowledge," implies that when he says "know," he does not mean that we can adequately know; all we know is, that His love exceeds far our knowledge of it, and with even our fresh accessions of knowledge hereafter, will still exceed them. Even as God's power exceeds our thoughts (Eph 3:20).

filled with—rather, as Greek, "filled even unto all the fulness of God" (this is the grand goal), that is, filled, each according to your capacity, with the divine wisdom, knowledge, and love; "even as God is full," and as Christ who dwells in your hearts, hath "all the fulness of the Godhead dwelling in Him bodily" (Col 2:9).
