Second Thessalonians 1

Suffering severe persecution, the Thessalonian saints were apparently persuaded, perhaps by a forged letter, that the day of the Lord had come (2 Thess. 2:2). In the first chapter Paul points out that a day of judgment is indeed coming on those who obey not the Gospel (2 Thess. 1:8). The Thessalonian saints were believers, and it was their persecution which gave testimony to that (2 Thess. 1:5). However, not only was it not the day of the Lord, but also, when that day would come, it would bring judgment on their tormentors!
