It's several things. It's a gathering of old mythology and parables from several previous religious traditions. It's an account of the travels and political and military activities of 12 Hebrew tribes. It's books about a number of their prophets. It's a collection of further books about the life of Jesus. It's got sections which are in the form of poetry, poetry which was once sung to musical accompaniment (like the Psalms). It's a bunch of proverbs. It's got some romantic poetry in it (the Song of Solomon). It's a collection of letters written to churches in the early Christain era. And it's got some prophecies and visions in it (like Revelations).

I'd say you could look at it a whole bunch of different ways, depending on what interested you...and how profound you think it is is strictly a matter of your own personal opinion. Some people think Ayn Rand is profound...
