Yea, we jw's like to 'brag' about how know our bible when in reality we know very little about the bible and very much about jw interpretation of the bible. There are around 35,000 verses in the bible and as jw's we probably use only about 75 of them. But we know those 75 by heart because they are repeated over and over and over in the literature and meetings!
Before I started my fade in earnest, I began to have those nagging doubts so I started reading the bible in hopes that my doubts would disappear. What an eye opener to actually read the bible without the jw filter glasses.
My conclusion is that the bible is just Jewish mythology. It was written by Jews, about Jews, and for Jews. Every ancient civilization has there lore, legend, and heroes. The bible is the Jewish record of theirs'.
just saying!
