When I first left I still believed the Bible was the word of god, and that there must be a true (christian of course) religion out there. I searched for one, for a while, all contained errors or faults. I examined non-christian faiths, all were wacky.
I then decided that I would lead an evidence based life, to me it was the only way that made sense, and the only way to avoid being mis-led.
I examined the Bible properly, and found it was entirely the work of men.
I then searched for evidence of god....none. Then for evidence of a designer/creator........... none, that satisfied me and my criteria.
Faith, believing that something is true without satisfactory evidence, is not for me, and I cannot see any difference between it and Delusion.
