I was listening to one of my favorite podcasts yesterday and they had a great discussion around the question of "Has science explained God away?". In the discussion they, the scientific/atheist side, expressed their complaint that believers will far to often sit back on the "John did it" type of reasoning.
Being conscience of our own skewed perception in the belief process is akin to wearing glasses to correct our vision. My ability to perceive, to know and to understand truth is limited to my ability of perception. My perception is influenced through culture, imprinting, experience, fears and desires.
