The church in Thessalonica was facing lots of struggles and persecution because of their faith. Paul lived it first hand in Acts 17:1-9. After escaping Thessalonica and then Berea, Paul took off for Athens and then Corinth. During his time in Corinth he sent two letters back to the church in Thessalonica over approximately 6 months. In both he expresses his concern for them, and encourages them to keep going in their faith, even though life had gotten so hard for them. In 2 Thessalonians Paul gives instruction about Jesus's return and to not be a lazy Christian. Keep going; Jesus will return, so keep working until he does!
