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?

unto the Father—The oldest manuscripts omit "of our Lord Jesus Christ." But Vulgate and some very old authorities retain them: Eph 3:15, "From whom," in either case, refers to "the Father" (Patera), as "family" (patria, akin in sound and etymology) plainly refers to Him. Still the foundation of all sonship is in Jesus Christ.
