Everyone has to decide for him or herself what's true and what's not.
Its not a simple decision. And, the answers are not all there....
The answer of whether you believe something is true is there. Penn Gillette puts it best:
Do you know whether a god exists? no
Do you believe a God exists? no
Unless someone is an arrogant ass, the first question should always yield a 'no'. The second question is where believers and the non-blind diverge. If my best friend tells me he has an omnipotent invisible friend who judges his every thought and punishes him by hurting the people around him, do I really know whether he's lying? No. Do I believe him? No.
I was a Fundie Baptist for a large portion of my life. I converted to LDS about the time I was twelve and living with my mormon grandmother. When I was 17, I started attending a Fundie Baptist church again after I moved back in with my mother (loose history). When I was 20 and in college, I read Atlas Shrugged
. Rand's criticism of spirituality initially turned me off to her message, but it planted the seed. I could no longer read the bible in the same light and soon couldn't even pray without feeling stupid. I read the Case for Christ, but that made it worse and Sam Harris' Letter to a Christian Nation
finally tipped the scales. I find it amazing that otherwise intelligent people can possibly believe such obvious mythology and superstition, but it attests to the power of a dogmatic upbringing and the manipulation of guilt. It disgusts me.
