I answered 75% ... I realize that I lie in bed at night and think about the vastness of the universe, about how absurd it is that I'm even alive and capable of wondering at my own existence; and I realize that logically, I shouldn't believe in God. But something keeps drawing me back. And it's not that it's what my parents taught me--me and my parents definitely don't agree on everything, even though we go to the same church. I don't discount science, I'm not a rabid anti-evolutionist or anything, but for me science fails to answer the deeper "why" of "Why do I exist?"
Honestly, I found my freedom in God by abandoning my old view of Christianity. And the farther away I move from my old view (I was a pretty good bible-thumper up until the age of fifteen or so), the more I realize that All I know is that I don't know nothin'. Hence the 75% thing. If I get to the point where I mark yes, I 100% absolutely know for a fact that everything that I believe right now is one hundred percent true (what is truth, anyway? nobody's answered me yet ... =P), then I've gotten arrogant with myself. I know that's how I am because I've been through it before--I'm definitely not saying that that's how everyone else is.
So yes. That's how I see things.
