Take a look at Moses in Exodus 3: 6
And he said, "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob." And Moses hid his face, for he was afraid to look at God.
and 3:12-13
Now therefore go, and I will be with your mouth and teach you what you shall speak." But he said, "Oh, my Lord, please send someone else."
Now look at Exodus 33:15, 18
And he said to him, "If your presence will not go with me, do not bring us up from here"... Moses said, "Please show me your glory."
And be inspired.
