The “Holy Bible” itself claims to be inspired by God. It is a library of 66 books (39 in the OT and 26 in the NT), written by many different authors and it contains several different types of books (prophecy, history/narrative, poetry, wisdom, psalms, laments, apocalyptic, autobiography/biography, letters etc.). The Lord speaks to you through all these different types of literature but it does help to be able to recognise them.
