3:1-4 As Christians are freed from the ceremonial law, they must walk the more closely with God in gospel obedience. As heaven and earth are contrary one to the other, both cannot be followed together; and affection to the one will weaken and abate affection to the other. Those that are born again are dead to sin, because its dominion is broken, its power gradually subdued by the operation of grace, and it shall at length be extinguished by the perfection of glory. To be dead, then, means this, that those who have the Holy Spirit, mortifying within them the lusts of the flesh, are able to despise earthly things, and to desire those that are heavenly. Christ is, at present, one whom we have not seen; but our comfort is, that our life is safe with him. The streams of this living water flow into the soul by the influences of the Holy Spirit, through faith. Christ lives in the believer by his Spirit, and the believer lives to him in all he does. At the second coming of Christ, there will be a general assembling of all the redeemed; and those whose life is now hid with Christ, shall then appear with him in his glory. Do we look for such happiness, and should we not set our affections upon that world, and live above this?
3. The Greek aorist tense implies, "For ye have died once for all" (Col 2:12; Ro 6:4-7). It is not said, Ye must die practically to the world in order to become dead with Christ; but the latter is assumed as once for all having taken place in the regeneration; what believers are told is, Develop this spiritual life in practice. "No one longs for eternal, incorruptible, and immortal life, unless he be wearied of this temporal, corruptible, and mortal life" [Augustine].
and your life … hid—(Ps 83:3); like a seed buried in the earth; compare "planted," Ro 6:5. Compare Mt 13:31, 33, "like … leaven … hid." As the glory of Christ now is hid from the world, so also the glory of believers' inner life, proceeding from communion with Him, is still hidden with Christ in God; but (Col 3:4) when Christ, the Source of this life, shall manifest Himself in glory, then shall their hidden glory be manifest, and correspond in appearance to its original [Neander]. The Christian's secret communion with God will now at times make itself seen without his intending it (Mt 5:14, 16); but his full manifestation is at Christ's manifestation (Mt 13:43; Ro 8:19-23). "It doth not yet appear (Greek, 'is not yet manifested') what we shall be" (1Jo 3:2; 1Pe 1:7). As yet Christians do not always recognize the "life" of one another, so hidden is it, and even at times doubt as to their own life, so weak is it, and so harassed with temptations (Ps 51:1-19; Ro 7:1-25).
in God—to whom Christ has ascended. Our "life" is "laid up for" us in God (Col 1:5), and is secured by the decree of Him who is invisible to the world (2Ti 4:8).
