Are Paul's letters a progressive revelation?
The Apostle Paul's Church letters, especially the seven Church letters, are themselves a progressive revelation from the beginnings of his writings to the end. They follow the format of first doctrine, then reproof, then correction, and finally instruction in righteousness.
Les explains that all Scripture from Genesis to Revelation is a progressive revelation. As people came up through the Old Testament, God kept revealing things the earlier fellows did not know. In the New Testament, God revealed things not in the Old Testament, and especially through the Apostle Paul, revelations never hinted in the Old Testament and things Jesus never spoke of. Within Paul's letters, especially the seven Church letters, there is again a progressive revelation from the beginnings of his writings to the end, under the format of first doctrine, then reproof, then correction, and then instruction in righteousness. Les points this out to show how beautifully the Book is put together, noting Paul did not sit down planning to put doctrine first or write in reproof; he likely did not even realize he was writing Scripture.
