"No other writings of Paul provide a greater insight into his missionary methods and message as 1 and 2 Thessalonians," says Leon Morris. "Here we see Paul the missionary at Paul the pastor, faithfully proclaiming the gospel of God, concerned for the welfare of his converts, scolding them, praising them, guiding them exhorting them, teaching them; thrilled with their progress, disappointed in their slowness . . . Especially important is the teaching of these Epistles on eschatology."
