Meh, I don't. To me personally, the notion of a god is more a poetic vehicle than anything else, an expression of hope or despair. I do sometimes raise my hands to the sky or whatever, as some kind of recognition that there are things beyond our control. There is luck, good and bad, there is the unknown, but 'a' god, nah. Hope, pray, wish, it's all the same.
I don't consider myself an atheist too for that matter, or an agnostic or whatever. I'm just… nothing. Or I'm just me, to make it sound a bit more positive; a human being. I don't need to have a full fledged analysis of everything, rational or irrational. Not everything can be explained, nor does it need to. If I feel it, I feel it; I don't need to know why.
I'm not saying I'm not a spiritual being though; everybody is a spiritual being. You don't have to go to church for that, or read the right books, or get on your knees or stare at a wall, wear the accompanying accroutrements or follow a particular diet or any of those things. It doesn't matter if you read the Bible or the Bhagavad Gita or Biggles, go to temple or CBGB's, light incense, candles or cigarettes, drink corner shop piss or Ayurvedic Yogi Tea®. None of that matters, and it doesn't necessarily make people any more (or less) spiritual, more (or less) pure, or provide them with some kind of spiritual authority over others, which, in the end often turns into a vehicle to judge and put people down, at least in my experience. Whatever works is good, and try to do the right thing along the way.
I just believe in… me, or at least I try to, and I believe in those few people whom I connect with on some level, or even truly love and I do feel a great reverence to whatever moves me. That's enough for me, that's really all I need. Those are the things that get me through, which is probably what the whole god concept is supposed to be about anyway.
Actually, there is a Lennon song that sort of sums it up for me...
