Favorite Books In Relation To Faith (other Than The Bible).

What are some of your favorite books about, that touch on, or support faith? These can be books that indirectly point to God, they can be books that very directly point to God. These can be books that have nothing to do with faith but have spoken to you in a very spiritual way. They can be any genre, fiction or non-fiction. It can be a singular book or a series.

BUT I am talking about books outside of the Bible.
