The Bible is the story of God's dealings with His creation.  Through it we learn about God, what He is like, how He deals with us, what He has done for us and what He has promised us.  St. Paul teaches us that "All Scripture is given by inspiration of God..." (2 Timothy 3:16).  This means that there is only One author for the Bible Who is the Holy Spirit.  The Holy Spirit however used many people's pens to write it.  David the Psalmist describes this saying "My tongue is the pen of a ready writer" (Psalm 45:1).

The Bible is also God's written word.  To me.  Now.  The Holy Spirit talks to us through the Bible and send us very personal messages.  The Bible is a personal letter from God to me.  Whenever I want to hear God's voice I should read His word.  It is by God's grace that we have His words recorded for us and readily available for us to read again and again.

Even though the Bible might appear to be limited in the number of books, chapters and verses, it is however unlimited in its depth.  One can spend an entire lifetime learning and studying a single book, chapter or a verse and not be able to finish it.  Some of the desert monks might spend months and years just trying to understand and apply a portion of a verse.  Nobody can ever say that they have finished reading the Bible.  There will be always new messages, new lessons and new wisdom that could be extracted from the Bible.

There are many different methods in studying the Bible.  There's the historical method, topological method, character study method, etc...  It is important however not to study any part of the Bible out of its proper context.  Each verse is related to its surroundings, each paragraph is related to the previous and the next, each chapter is related to the previous and the next, etc...  The key is to understand this relationship.
