I don't currently subscribe to theologically conservative, inerrant Christianity because I find -- from what is admittedly only a theologically-uneducated layman's POV -- vast chunks of the Bible to be either internally inconsistent or historically inaccurate. I do think there could be validity to theologically liberal, non-inerrant forms of Christianity, though.
I also don't subscribe to atheism. I find it presumptuous to reach such a conclusion when mankind hasn't even reached full understanding of the physical universe, let alone what might be beyond it. Also, on a more emotional note, I'm not comfortable with the nihilism I believe is inherent in an atheistic universe.
As for other religions/metaphysical worldviews, I don't know enough to reach a conclusion on them. All I can say is that, from a superficial reading of them, some are more appealling to me than others.
I'm not really comfortable with my agnosticism -- I want to believe in God -- but in lieu of objective or subjective evidence for such an entity, I find cautious indecision to be the best course of action at this time.
