Well, I believe that "God" is just a concept. A way for human beings to try to understand the world around them. Therefore, yes I believe that "God's" nature is in Nature.
Random, but all random things happen for a reason, the purpose of balance. The natural world is full of balance. Animals breathe in oxygen, breathe out carbon dioxide. Plants take in carbon dioxide, and create oxygen. A creature dies, rots, and creates fertilizer for another life form, plants.
That, in my opinion, is the nature of "God."
