...your faith against mine, shaman...
Prove God does not exist. Make me lose my faith. I dare you. Bring your A-Game. Bring your friends. Keep it confined to this cage, please. There are no rules, except you cannot take my God's name in vain, as previously noted.
Extra credit for proving He exists. If you claim to be Christian, act like one. I am an acknowledged Bad One, and it is my blog. Mind your manners.
