Just to clarify--It's not a book that just anyone can read and suddenly they know God.
The Old Testament (also known as the Jewish Tanakh) is the first 39 books in most Christian Bibles. The name stands for the original promise with God (to the descendants of Abraham in particular) prior to the coming of Jesus Christ in the New Testament (or the new promise). The Old Testament contains the creation of the universe, the history of the patriarchs, the exodus from Egypt, the formation of Israel as a nation, the subsequent decline and fall of the nation, the Prophets (who spoke for God), and the Wisdom Books.
