The Two Ages are the biblical division of redemptive history into "this age" (Greek aiōn houtos) and "the age to come" (aiōn ho mellōn). This age is the present world under sin’s reign, ruled by "the god of this world" (2 Corinthians 4:4), "the prince of the power of the air" (Ephesians 2:2). The age to come is the consummated kingdom under Christ’s manifest reign, beginning at His return: "the powers of the world to come" (Hebrews 6:5); "and these shall go away into everlasting punishment: but the righteous into life eternal" (Matthew 25:46). The Christian lives in the overlap — the age to come has already broken in through Christ’s first advent, and is awaiting consummation at His second.
(Composite.) The biblical division of redemptive history: this age (present, under sin) and the age to come (consummated kingdom).
Christ's teaching (Mt 12:32, 13:39-40, 13:49, 24:3, 28:20; Mk 10:30; Lk 16:8, 18:30, 20:34-35) repeatedly contrasts the two.
Paul develops it (Rom 12:2, 1 Cor 1:20, 2:6-8, 3:18, 2 Cor 4:4, Gal 1:4, Eph 1:21, 2:2, 6:12; 2 Tim 4:10) as the controlling framework for understanding the saint's situation.
Matthew 12:32 — "Whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come."
Ephesians 1:21 — "Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come."
Hebrews 6:5 — "And have tasted the good word of God, and the powers of the world to come."
Galatians 1:4 — "Who gave himself for our sins, that he might deliver us from this present evil world."
Modern Christianity often loses the two-ages framework; without it, the New Testament's eschatology becomes incomprehensible.
The two ages were Jewish before they were Christian. Second-Temple Jewish thought distinguished olam hazeh (this age) from olam haba (the age to come). The New Testament inherits and Christianizes the framework.
The Christian innovation: the age to come has already begun in Christ's resurrection and Spirit-pouring. The saint lives in overlap — this age still around, the age to come already irrupting through Christ. The pattern is already-not-yet.
