Christians claim the Bible is the Word of God, that it is the final authority in all matters relating to Christian faith and practice, and that it is absolutely reliable in all that it teaches. But to put such confidence in the Bible requires that we have the correct books in the Bible. But do we? Why are the 66 books in the Bible in the Bible, and why were other books that could have been included not included? This subject is very important and complicated, so complicated it takes three volumes to fully cover it. Volume One studied the books included in the Old Testament (OT) and considered other books that could have been included but were not. This Volume Two will cover the books included in the New Testament (NT). Volume Three will then consider the writings of the Apostolic Fathers, some of which were considered for inclusion in the NT, along with other writings, orthodox and Gnostic, that many wonder why they are not included in the NT. In this second volume, each of the 27 books included in the NT will be reviewed in detail. Who wrote them and when, their theology, and other pertinent background information will be discussed to explain why they were included in the NT. Arguments against the traditional viewpoints on these books will be addressed.
