First & Second Thessalonians- Everyman's Bible Commentary: Everyman's Bible Commentary

Dr. Ryrie's admiration for these letters is clear: "These epistles are like finely cut gems From every part shine forth the character and conduct of Paul's missionary heart, and they sparkle with the brilliance of captivating power of the Gospel of Christ."
Paul's was basically satisfied, even thrilled, with the progress of his flock. But he wanted to encourage them to go on in their faith, to be strong in persecution, wary of temptation, and watchful for the Lord's Second Coming.

In Charles Ryrie's timeless commentary on 1 and 2 Thessalonians, the great theologian illuminates Paul's clear teaching for his strong but not infallible church in the powerful, sensual city of Thessalonica. He shows how the apostle had to defend himself and his conduct from charges of slander, and how Paul was pleased with his recent converts and their vibrant, durable faith.
But despite Paul's favor, he wanted to clear up some misconceptions the young church had about the Second Coming of Christ. In these two letters, he corrects confusion about when Christ would come back, and more important, he bolsters the hearts of this persecuted flock with the glorious hope of Christ's resurrection, his return, and eternal life."
