More Than Sufficient...

But Moses said to God, "Who am I that I should go to Pharaoh and bring the children of Israel out of Egypt?" He said, "But I will be with you, and this shall be the sign for you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.
Exodus 3:11, 12 (emphasis added)

Significantly, God does not answer Moses' surface question by reassuring him of his educational background, leadership potential, or other talents that might qualify him for this job. To Moses' question, "Who am I?" God responds with, "I will be with you." The promise of divine presence is more than sufficient for all challenges and obstacles. Moses' qualifications are irrelevant--God will make it happen. The promise of divine presence signifies the transfer of the holy, consuming fire from the bush to Moses and his people.
