There is the essence of God and there are the attributes of God. The essence is impossible for us to understand. We can begin to understand the attributes. In fact, part of a Sufi education is to understand those attributes in yourself. God has said, "My servants will find Me as they see Me." This does not mean if you think of God as a tree or as a mountain that God will be that tree or mountain. If you think of God as merciful, or loving, or as angry or vengeful, that is how you will find God.
