God revealed Himself as “I AM” through the burning bush to Moses. Besides John 1:1, this is the greatest revelation to Whom God is before the expounds of Christ. Moses had asked the Father, “who shall I say that you are?” and the Father could only theologically reply “I AM”.
Why?
It is because God has no contingency. He is Himself, not a cluster of components that creates a whole. He simply IS.
