Titus 2:13

(Phi 3:20-21). Looking for--with constant expectation (so the Greek) and with joy (Rom 8:19). This will prove the antidote to worldly lusts, and the stimulus to "live in this present world" conformably to this expectation. The Greek is translated, "waiting for," in Luk 2:25. that--Greek, "the." blessed--bringing blessedness (Rom 4:7-8). hope--that is, object of hope (Rom 8:24; Gal 5:5; Col 1:5). the glorious appearing--There is but one Greek article to both "hope" and "appearing," which marks their close connection (the hope being about to be realized only at the appearing of Christ). Translate, "The blessed hope and manifestation (compare Note, see on Tit 2:11) of the glory." The Greek for "manifestation" is translated "brightness" in Th2 2:8. As His "coming" (Greek, "parousia") expresses the fact; so "brightness, appearing," or "manifestation" (epiphaneia) expresses His personal visibility when He shall come. the great God and our Saviour Jesus--There is but one Greek article to "God" and "Saviour," which shows that both are predicated of one and the same Being. "Of Him who is at once the great God and our Saviour." Also (2) "appearing" (epiphaneia) is never by Paul predicated of God the Father (Joh 1:18; Ti1 6:16), or even of "His glory" (as ALFORD explains it): it is invariably applied to CHRIST'S coming, to which (at His first advent, compare Ti2 1:10) the kindred verb "appeared" (epephanee), Tit 2:11, refers (Ti1 6:14; Ti2 4:1, Ti2 4:8).
