The spiritual sense of Bible reading

Most Christians read the Bible in a spiritual sense, trying to find its deeper spiritual meaning.  What can the Bible do to help my spiritual life?  What is the deeper significance of a particular text?  What is it telling me about God and Jesus?  How do the Old and New Testament fit together?  How were the prophecies fulfilled?  Are there any allusions to Christ in the Old Testament?  Can I find an allegorical sense to various stories?
