A.T. Robertson Commentary 2 Timothy 1:10

"but hath now been manifested by the appearing of our Saviour Christ Jesus, who abolished death, and brought life and immortality to light through the gospel," — 2 Timothy 1:10 (ASV)

But hath now been manifested (φανερωθεισαν δε νυν). First aorist passive participle of φανεροω agreeing with χαριν. See Tit 1:3; Colossians 1:26; 3:4 for φανεροω and the contrast made.

By the appearing (δια της επιφανειας). Only here of the Incarnation (except the verb, Titus 2:11; 3:4), but for the second coming see Tit 2:13.

Who abolished death (καταργησαντος μεν τον θανατον). First aorist active participle of καταργεω, the very phrase in 1 Corinthians 15:26; Hebrews 2:14.

Brought to light (φωτισαντος δε). First aorist active participle of φωτιζω, literary Koine word for which see 1 Corinthians 4:5; Ephesians 1:18, to turn the light on.

Life and incorruption (ζωην κα αφθαρσιαν). The opposite of θανατος, "life and immortality" (unchangeable life).
