People all over the Roman world began to imitate these common first-century pagan converts to Christianity because of their radical transformation and their steadfast devotion to the Lord. By writing them a letter to strengthen their faith and demonstrate his love for them, the apostle Paul commends their devotion. We can learn insightful ideas from Thessalonians by using Mark Wallace's book, 1 Thessalonians (The Good Book Guide). It is a study guide that was specifically designed to be understandable by everyone. It works well as devotional and as small group study material. This book enlightens us about our calling to live holy and blameless lives in the midst of suffering and persecution.
