Ephesians 2:7

That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.

[ Endeixeetai (G1731)] 'That He might show forth (middle reflexive voice: for His own glory, Ephesians 1:6; Ephesians 1:12; Ephesians 1:14) in the ages which are coming on' - i:e., the blessed ages of the Gospel which supersede 'the age [ aioona (G165), "course"] of this world' (Ephesians 2:2), and the past "ages" from which the mystery was hidden (Colossians 1:26). These good ages, beginning with the first preaching of the Gospel, and thenceforth continually succeeding one another, are not consummated until the Lord's coming again (cf. Ephesians 1:21; Hebrews 6:5). The 'coming on' does not exclude the time then present, but implies the ages following upon Christ's 'having raised them up together' (Ephesians 2:6).

Kindness, [ chreestoteeti (G5544)] - 'benignity.'

Through Christ - Greek, 'in Christ;' as often, to mark that all our blessings center 'IN HIM' as their source. Hence, "Christ" is so often repeated.
