God knew it was imperative for Moses to know who He was - that He was I AM. I AM is the present tense, active form of the verb to be. As God's name , it declares that He is unchanging, constant, unending, always present, always God.

God was telling Moses:

I AM the centre of everything.

I AM running the show.

I AM the same every day, forever.

I AM the owner of everything.

I AM the Lord.

I AM the Creator and Sustainer of life.

I AM the Saviour.

I AM more than enough.

I AM inexhaustible and immeasurable.

I AM God. 

In a heartbeat, Moses knew God's name-and something more. He finally knew his. For if God's name is I AM, Moses' name must be I am not.

I AM not the centre of everything.

I AM not in control.

I AM not the solution.

I AM not all powerful.

I AM not calling the shots.

I AM not the owner of everything.

I AM not the Lord. 

That's my name, too. And yours. I am not. Just try it under your breath, "My name is I am not."

I am not running anything.

I am not the head of anything.

I am not in charge of anything.

I am not the maker.

I am not the saviour.

I am not holding it all together.

I am not all-knowing.

I am not God.
