Call to remembrance (anamimnēskesthe). Present middle imperative of anamimnēskō, as in 2Co 7:15 “remind yourselves.” The former days were some distance in the past (Heb 5:12), some years at any rate. It is a definite experience of people in a certain place. Jerusalem Christians had had experiences of this nature, but so had others.
After ye were enlightened (phōtisthentes). First aorist passive participle of phōtizō in the same sense as in Heb 6:4 (regeneration) and like “the full knowledge of the truth” in Heb 10:26.
Conflict (athlēsin). Late word from athleō, to engage in a public contest in the games (2Ti 2:5), only here in the N.T. It occurs in the inscriptions. Cf. Heb 2:10 for the benefit of “sufferings” in training.
