WHAT IS GOD?

In a forum like this there are bound many discussions on the existence of "God".  The discussions have little meaning though if every participant is discussing a different concept when they use the word "God".  Maybe here we can see some of the differing opinions of the concept of "God" and perhaps settle on some definition that can at least make our discussions more meaningful.

Some examples of differening concepts of god:

The personal God - an intelligent being/force that interacts with humans on a personal level

The creator God - an itelligent being/force that cretaed the universe, but has left us free to do as we please

God as truth - the only absolute trouth in a world of chaos and uncertainty, not necessarily a being

God as the Undifined - everything that we, as humans, cannot understand or comprehend about reality

These are just some examples. What is your definition of "God"?
