Romans 8:17
17. And if children, then heirs—"heirs also."
heirs of God—of our Father's kingdom. and joint-heirs with Christ—as the "First-born among many brethren" (Ro 8:29), and as "Heir of all things" (Heb 1:2). if so be that we suffer—"provided we be suffering with Him." that we may be also glorified together—with Him. This necessity of conformity to Christ in suffering in order to participate in His glory, is taught alike by Christ Himself and by His apostles (Joh 12:24-26; Mt 16:24, 25; 2Ti 2:12).Colossians 3:2-3
2. Translate, "Set your mind on the things above, not on the things," &c. (Col 2:20). Contrast "who mind earthly things" (Php 3:19). Whatever we make an idol of, will either be a cross to us if we be believers, or a curse to us if unbelievers.
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).2 Timothy 2:11-12
11. Greek, "Faithful is the saying."
For—"For" the fact is so that, "if we be dead with Him (the Greek aorist tense implies a state once for all entered into in past times at the moment of regeneration, Ro 6:3, 4, 8; Col 2:12), we shall also live with Him." The symmetrical form of "the saying," 2Ti 2:11-13, and the rhythmical balance of the parallel clauses, makes it likely, they formed part of a Church hymn (see on 1Ti 3:16), or accepted formula, perhaps first uttered by some of the Christian "prophets" in the public assembly (1Co 14:26). The phrase "faithful is the saying," which seems to have been the usual formula (compare 1Ti 1:15; 3:1; 4:9; Tit 3:8) in such cases, favors this.12. suffer—rather, as the Greek is the same as in 2Ti 2:10, "If we endure (with Him)" (Ro 8:17).
reign with him—The peculiar privilege of the elect Church now suffering with Christ, then to reign with Him (see on 1Co 6:2). Reigning is something more than mere salvation (Ro 5:17; Re 3:21; 5:10; 20:4, 5). deny—with the mouth. As "believe" with the heart follows, 2Ti 2:12. Compare the opposite, "confess with thy mouth" and "believe in thine heart" (Ro 10:9, 10). he also will deny us— (Mt 10:33).
