Again, Thief is putting these words into God's mouth, making things up. The Bible is a mixture of allegory, myth, and bits and pieces from the real teachings of Yeshu. 'I Am' is part of Yeshu's original mystical teaching, but that God spoke and there was light, etc. is part of the allegory.
It is a common mistake to think that the statement "I Am" is referring to the "I" self; the ego; the personal self. It is not. It refers to eternal ego-less essence alone. The use of the word "I" is purely as a matter of convention, but meaning: "this statement is coming through this body-mind, not from it"
When theif uses it its a reference to christ being the word as a personal god. Thats how I understand it from him but he can correct me if I am off on that. I can understand it like tao but not with consciousness.
