Hi it's me, a guy who was a never-doubting die hard christian until about 14 years old when I sat down and intended to read the bible cover to cover.
I made it through every single word (and every John begat Bruce etc ect) until leviticus.
I had always been raised as a bible literalist, that every single word of the bible was either true or a "metaphor". Well, I'm dumb but not an idiot. And it's impossible for a sane person to read the whole old testament and come out thinking it's the same author as the new testiment.
Imo, christians are primarily people who haven't read the bible yet.
