Qiaochu_Yuan has it right - the vast majority of Christians do not constitute additional evidence.
Moreover, the Bible (Jewish, Catholic, or Protestant) describes God as an abusive jerk. Everything we know about abusive jerks says you should get as far away from him as possible. Remember that 'something like the God of the Bible exists' is a simpler hypothesis than Pascal's Christianity, and in fact is true in most multiverse theories. (I hate that name, by the way. Can't we replace it with 'macrocosm'?)
More generally, if for some odd reason you find yourself entertaining the idea of miraculous powers, you need to compare at least two hypotheses:
*Reality allows these powers to exist, AND they already exist, AND your actions can affect whether these powers send you to Heaven or Hell (where "Heaven" is definitely better and not at all like spending eternity with a human-like sadist capable of creating Hell), AND faith in a God such as humans have imagined will send you to Heaven, AND lack of this already-pretty-specific faith will send you to Hell.
*Reality allows these powers to exist, AND humans can affect them somehow, AND religion would interfere with exploiting them effectively.
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
