God’s being is also something totally unique. It is not just that God does not need the creation for anything; God could not need the creation for anything. The difference between the creature and the Creator is an immensely vast difference, for God exists in a fundamentally different order of being. It is not just that we exist and God has always existed; it is also that God necessarily exists in an infinitely better, stronger, more excellent way.
The difference between God’s being and ours is more than the difference between the sun and a candle, more than the difference between the ocean and a raindrop, more than the difference between the arctic ice cap and a snowflake, more than the difference between the universe and the room we are sitting in: God’s being is qualitatively different. No limitation or imperfection in creation should be projected onto our thought of God. He is the Creator; all else is creaturely. All else can pass away in an instant; he necessarily exists forever.
