"Pantheism is the belief that the universe (or nature as the totality of everything) is identical with divinity, or that everything composes an all-encompassing, immanent God. Pantheists thus do not believe in a distinct personal or anthropomorphic god" (Wikipedia).
That matches to my interpretation of your stated beliefs.
I believe that God exists as the Universe working within itself... and that as each of us live, we each experience God.
Most of the atheism stuff on this site has more to do with a god that is a discrete being with supernatural capabilities than the thing you describe. However, if the main reason that you're not an atheist is that you have trouble picturing a godless universe, and you change beliefs based on what you learn and hear about the world (good work, by the way), chances are good that you'll end up being an atheist if you spend enough time on this site. ;)
If you actually want to clarify your beliefs, it could help to imagine some different worlds and see whether they count as having God in them or not, in order to consider what constitutes the absence of God. If there's no scenario that counts as God not existing, then I'm not sure what your belief that "God exists" is supposed to represent, and what information about the world someone could derive from that belief, given that it was true.
Thanks so much for the data about party affiliation!
Also, if you count subconscious desires to act in one's own interest as "ulterior motives", you may like what Robin Hanson on Overcoming Bias has to say about signaling.
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves. (Step-by-step, foolproof instructions here; takes <180seconds.)
If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
