Would you be more impressed if God had said, "I am Fred"?

Yes. That would be a parsable sentence.

Yes. That would be a parsable sentence.

So is "I am the great I am". As is "I am the man who shot Liberty Valance". But in any case, God spoke Hebrew, not English when He spoke to Moses.

It isn't "I am that I am", it is simply "I AM".

"I AM" means He is self-existant. He is complete. Nothing can be added or taken away.

I always think "I AM all that there needs to be". When you get to know Him, you begin to realize that He is fulfillment.
