I think believers simply accept revealed truth and do not question their personal experiences. That is why I was a believer for so long and could not have changed that because it was just so obvious to me back then. Then I gave it a think and I could not believe now if I tried, and I have. Believers think that we choose not to believe the obvious you know, like how the tide goes in and the tide goes out. Also, how do magnets works? Fucking God! That's why!
