Yes, He is Mercy; we can only be merciful. He is Love; we can only love; He is goodness; we can only be good (through Him). We can never be Love, Mercy or Goodness.
The natural and supernatural are on different planes of existence, but we believe that Creation points to God Himself, and that Creation IS analogous, though only in images and likeness, not in reality
God does not exist; He is Existence. That which exists has a beginning and the end; God doesn't. Creation is evidence of God, for without God there is nothing.
Our existence is not analogous to God's. Nothing of ours is analogous to God. Nothing we do is analogous to God's work. If we do good, it is not ours, but God's.
So if I understand you, God's Energy is like a picture or an image of His essence - and yet, at the same time - IS God?
No, we are a picture of God (when we don't sin).
God's energies proceed from His nature and therefore are divine, just as ours are human.
So what I think you are saying is that our actions are not "us" properly, but for God, His actions are still God ontologically? His Actions and His Nature are both God while for man, his nature and actions are separate?
