"Our thoughts about God are just that: thoughts about God. They are not God. They approximate God. This includes the thoughts, now written, of the biblical writers and all theologians since. All their thoughts and all their writings are not God, but approximations of God." -David Haward (You can see more of David's work here.)This was when I began to differentiate between my thoughts and what God is. How I define God is just that, my definition. To embrace the idea that our thoughts are just approximation carries with it a humbling affect. It allows me to understand how someone else may view and define God (or anything else for that matter) differently. God then becomes malleable (a playdoh god, maybe?) able to change shape and grow depending on the viewer. This tells us more about ourselves than it does about God herself granting us another window into the heart of our neighbor. Is there a God beyond our personal playdoh god? Sure, why not, who knows. Does it matter? That depends how important it is to you for your thoughts about God to be real.
This is something most people don't readily think about because it introduces a sliver of doubt on what they consider to be the foundation of their beliefs. But doubt is not the "gateway drug" which leads down the slippery road to Atheism, it is a constructive tool which helps us analyze our beliefs. Analyzing what we believe helps us to better understand why we believe the things we believe. Would you rather accept a belief system you simply inherited from your parents and/or environment or would you like the chance to choose what you believe for yourself? In the end we decide what religion to follow (or not follow), which house of worship to attend, and what spiritual practices to practice. In the end we make our choices based on our thoughts after weighing the evidence we analyzed. Now multiply that process by several billion people and it becomes clear that our thoughts about God are simply that, our thoughts.
