If God were a Tree

If God were a Tree, what would be His Spirit? Think of God as a Tree and the Spirit as the Shade of the Tree. Just like the Shade would not exist without the Tree, even so the Spirit of God would not exist without God.

The Spirit does not exist independently - it's a byproduct, just as the Shade of the Tree is a byproduct of the limbs and leaves of the Tree blocking the light rays of the sun.
