Ever met someone who thought they were humble because they believed they were inferior? Enter Moses, stammering, stumbling, and so like us in so many ways. Some people rely on their own merit, and we know they are proud. Others think they are worthless, helpless, inept, inferior, and we think maybe they are not proud. They think they are not proud. But really, there's no difference between the two. Neither are relying on God. To be humble is to be completely and utterly reliant on God.
The first thing Moses says when the bush speaks is "Here am I." The second thing he says is "Who am I."
God has just spelled out his plan, and Moses is nervous. Honestly, who wouldn't be? But He gives him verse 12, and that changes everything. "Certainly, I will be with thee."
And then God identifies himself.
"I Am that I Am"
If there were one characteristic of God that showed him most powerful--one thing that could rise above the rest and answer every question that has ever been asked about him, It's found in Exodus 3.
I Am that I Am
It answers the question: Is there a God?
It shows his existence spanning both directions through eternity.
It answers the question: Where is God?
It shows his presence in every place and every time simultaneously.
It answers the question: Why God?
Why did you allow this. Why do you allow pain and heartache and injustice? Because He is God. He owes no explanation.
It answers the question: Is God able?
It shows God's magnitude. He is a God as omnipotent and omniscient as he is omnipresent. He is a God as great as he is eternal. He cannot be contained by my perceptions or limited in his Godness.
He is God.
He Is that He Is.
