On the New Testament: Free Chapter

Who Wrote the New Testament?
On one hand, the twenty-seven books of the New Testament were written by at least eight human authors. In most of the books, the author clearly identifies himself. The only exception is the book of Hebrews, which some believe Paul wrote, but this can only be inferred since the author is not mentioned in the book.
On the other hand, the human authors of Scripture are not the only authors of Scripture. God communicated through the authors of Scripture in a real and miraculous way so that his divine truth could be perfectly communicated through men. In this way, the divine and human authorship of Scripture is very much like Jesus himself, who was both fully God and fully man. God the Father chose to work through the humanity of Jesus to reveal himself to us in a manner akin to how he had previously revealed himself to us as God through the men who wrote the Old Testament.
