Self (Itself) is God.

That which is is God; God (it)Self is. What it means is that God is always Good for it itself 'is'; it 'is' itself. This, in turn, leads to the realization that God is Self(-Existent) and the understanding that Self itself is (all without separation aka) God, hence why it is said that God is One for Oneself is God. My God indeed... all is God.
