The five letters - from 1 Thessalonians to Titus - form a discipleship training school for anyone who wants God to transform their life. Paul was forced to flee the city of Thessalonica so quickly the he wrote 1 Thessalonians as the first lesson in his discipleship training school, teaching us how to be true converts. He was unable to return so he wrote 2 Thessalonians as a second lesson, which teaches us how to be true warriors. The last three letters were to individual graduates: Titus lays out the syllabus which we need in order to be truly fruitful; 1 Timothy explains how his young graduate can help the Ephesians to become truly mature in their faith and 2 Timothy acts as Paul's final will and testament in which he assures his converts that they are truly ready to continue the work after his death.
