To me Moses is all men grown to gigantic proportions.
He was a man of immense ability, immense emotions, immense humanness and immense dedication. There is something of Moses in each of us - the more there is, the better we are.
It is interesting to note that once Moses climbs Mt. Sinai and talks to God there is never contentment for him again. That is the way it is with us. Once we talk to God, once we get his commission to us for our lives we cannot be again content. We are happier. We are busier. But we are not content because then we have a mission - a commission, rather.
