This letter from the apostle Paul was probably written shortly after his first letter to the church in Thessalonica. He had been boasting of them to other churches, telling of their faith and their love for each other in the face of persecution. Paul reminded them that God will repay their persecutors. He also addressed two recurring problems in this church. First, as seen in 1 Thessalonians, they were concerned that the Lord had already returned. Paul urged them not to become “shaken in mind or alarmed,” fearing that “the day of the Lord” (2:2) had already come. Second, he admonished them not to be idle, com-manding them that, “If anyone is not willing to work, let him not eat” (3:10).
