The Bible consists of 66 books. 39 in the Old Testament (OT), and 27 in the New Testament (NT). They were written over a period of some 1400+ years by at least 40+ authors. Yet they all have the same theme: they speak of Christ ~ Jn.5:39
Originally the scriptures would have been written down on scrolls in columns, the idea of chapters and verses is quite a [relatively] modern innovation. Like verses and chapters, outlines were not in the original text; they present, however, a useful guide to the message of the book. The suggested outlines are offered as guide in studying the scriptures.
This sections covers the New Testament Books.
