Any book is written to be read, and the Bible is no different.
If you go into a library or reputable bookshop books are grouped on shelves into various categories, between fictional and those of a factual nature.
Some books are written principally to inform, (e.g. history, astronomy, biographies etc.)
Others to provide a basis for dealing with or solving various issues (e.g. diet, medical matters, car and house maintenance, etc )
Some, possibly most, are of a transient nature, written to amuse or gratify the senses, i.e. novels.
And yet others are written offering guidance on how the authors believe we should live and conduct our lives.
These may comprise a whole range of different philosophies and religious or quasi religious systems.
