Why do Paul's letters stand at the center of the New Testament by themselves?
The letters of the Apostle Paul stand at the center of the New Testament by themselves because they are the part of the Word directed primarily to the Gentile Church, the Body of Christ. Other portions—the Old Testament, the Gospels, and early Acts—were directed to Israel under its auspices.
Les explains that he gives a little review because new viewers constantly come into the audience. The letters of the Apostle Paul stand in the center of the New Testament pretty much by themselves because this part of the Word is directed primarily to the Gentile Church, or the Body of Christ. By contrast, the Old Testament, the Gospels, and the early chapters of Acts were all directed to and under the auspices of the nation of Israel. When Israel continued to reject everything and would not believe Christ was the promised Messiah, God providentially took away their Temple, took away Jerusalem, uprooted the nation from the land, and dispersed them among the nations. He then turned instead to the pagan Gentile world beginning with the Apostle Paul.
