At the most basic of levels, what is the definition of a god? One I commonly see is possession of the "Three Omnis" - omniscience, omnipresence, omnipotence. If there is nothing that exists in any form or fashion outside of the observable universe, then matter and energy are a god - after all, they exhibit all of the omnis. No intelligence can exist outside of them - everything that is known or recorded is done with matter or energy as the medium of transcription. There is nowhere that matter and energy are not. All power that could ever possibly be exerted would have to be derived from the energy inherent within the observable universe. In my view, it's really hard to duck the idea that we all have to at least be pantheists.
I just go a step or two beyond this. Call me a mystic, but I see too much poetry in creation, from the smallest quantum scope to the grandest cosmic scope of the universe (or even multiverse), from mathematics to language to science, to settle for an idea of all this being the product of an impersonal god. And if a god is personal, such a god would by necessity be relational. How does this god relate to us?
For most all of human history, men and women have ascended to high places - whether mountains, hills, mesas or towers - in an effort to get closer to their god. But what if god took such an interest in what he/she/it created that god deigned to descend to the valley where we live, instead of expecting us to plod up to the pinnacle?
That is, in a nutshell, what we believe the mission of Jesus was - God experiencing firsthand the trials and travails of what it means to be a human being...being born among us so that He might be born within us. The idea that we, who in some mystical way bear His reflection, might be reconciled to our true identity and begin to realize the depth and breadth of our potential in service to others and piety before God is a very romantic thing.
There is much personal theology that I espouse, but most all of it stems from these basic ideas - that god (who- or whatever that is) is god, that I am not, and that the examples of my forebears compel me to acts of service, the provision of grace, and the bestowal of mercy in an often merciless world.
The fact is that everything that religion preaches and what one teaches man can not be called bad for humanity. Therefore, I do not see anything wrong with people trying or believing in God. Even if a person is an unbeliever, then having humanity, he will not be bad in relation to religious people.
