I changed the way I process things for sure. Hard thing to do!
Also most of the best run humanitarian campaigns have nothing to do with religion. I "think" they're better because they can focus on the real issues plaguing people instead of always doing things with the ulterior motive of converting people.
I'm super tired right now and I am tired of thinking about reasons why I left my religion but you asked what logical reasons and I am sure an NT would be more helpful than me with logic since I just go with what I see and process and feel...
-we know the speed of light. If the bible is the inherent word of God then you must believe in a literal 6 days, no other way around it. You take out that one truth and all the rest of it goes up for grabs. Either it's all true or it's not. That being said, it doesn't make logical sense that we are living in a 6,000 year old universe.
-Tower of Babel - C'mon... really? I suppose god changed the color of everyone's skin then too eh?
-the notion that an all powerful all knowing all supreme being would give a damn about an a colony of ants on one tiny planet.
I can go with Victor's description of my coming out of christianity being a conversion experience for sure.
That's the annoying thing about discussing religion with theists, you can't argue with them. They believe what they believe and that's all there is to it. It's been my experience that only through a time of self discovery can they free themselves from the bondage of faith and live without fear of god.
