The term canon is used to describe the list of books approved for inclusion in the Bible. It stems from a Greek word meaning “rod,” as in a straight stick that serves as a standard for measuring. Hence, to speak of the biblical canon is to speak of authoritative books, given by God, the teachings of which define correct belief and practice. Obviously, only books inspired by God should be received as canonical. The Bible before you includes 39 books in the Old Testament (OT). Are these the right books? Who wrote them? What were their sources of information? These questions are asked by friends and foes of biblical faith. The present essay will touch on such issues with an aim to bolster Christian confidence in the OT.
