2 Peter
This letter was a “reminder” to the readers of the truth of the Gospel, which they had received as against the attacks of false teachers who would pervert it. The author urges his hearers to remain steadfast even amidst persecution and reminds them that the Lord will keep His promises. He speaks of the “day of the Lord” (parousia) and of the necessity of keeping themselves “without spot and blameless” (3:14)
