It was actually when I reached out to the bible for support and specifically the NT. What happened, was really an accident and it turned into a very thorough review of the NT from a scholarly and historical standpoint - peeling back the layers. I devoured tons of work of scholars and historians of all different breeds and came to the conclusion, the NT had bits that were historical, but overall, it was not.
This stimulated me to review the entire Christian story and try to reconcile the same with the realities of the world and I simply couldn't do it, if I was honest with myself.
I acquired a lot of knowledge and I overlayed this new knowledge with realities and it didn't reconcile. When I believed, much of it was from being brought up that way and having a true desire and need to believe someone was looking out for me and that is powerful motivation, that was eventually superseded by reality.
