Just as the Son and Word of God "became flesh and dwelt among us" (John 1:14), so too the truths He revealed to the world took on the garment of human formulation and expression. These truths are contained in the books of the New Testament, which are written by different authors and, while all contain the same redemptive message for humanity, each expresses it through different historical and missionary conditions and with different linguistic and expressive means. The Introduction to the New Testament deals with the examination of these external historical and missionary conditions of the genesis of the 27 books, the author and purpose of each book, the content, and other related issues.
