I believe
What do you believe is true even though you can't prove it?
I believe that human beings are ultimately inherently good, despite their sometimes disgraceful display of ignorance and hatred.
I believe that there are senses other than the ones to which humans are attuned, true physical ways of passing sensory information. Call it a "sixth sense" if you will -- there's more to the universe than what we're aware of.
I believe that for every beauty I see, whether I capture it or don't, there is a beauty that surpasses it. This belief, honestly, is what keeps me believing in God.

Even when I thought that God turned his back on humanity with the Tsunami, I saw how quickly the world responded with a show of their own humanity, and I was reminded that He was there all the time.
