I believe that God is the embodiment of the human understanding of perfection. It is clear that nothing of this universe is perfect. It is impossible to draw a perfect circle, yet we all intuitively understand what a perfect circle is. The human mind seems drawn to the idea of perfection, yet all human endeavors to attain it are ultimately futile. This longing for perfection, which profoundly and uniquely human, is generally ascribed to a force that is not of this world. That force is God. Also, 100 words is not enough for this topic.
