Why did God send Moses to be a sheep herder in the desert?
God sent Moses to the desert to be a lowly sheep herder in order to bring him down from his lofty position as Egypt's second-in-command and reduce him to nothing. In the world's eyes, sheep were an abomination to Egyptians, so God could use a nobody to confront Pharaoh.
Les explains that God does not use the highly educated, highly polished, or intellectually apt people; very few, if any, fit that mold. God can only use what is nothing in the eyes of the world. Moses is the prime example: he had become second man in Egypt, the greatest nation then known, with power and authority over armies, civilian operations, road building, and bridges, and he thought he could lead the children of Israel out. Therefore God had to send him to the back side of a desert to be a smelly sheep herder. Sheep were an abomination in Egyptian eyes, and it was into that place of abomination that God put this servant to bring him down from his lofty position to nothing more than a lowly sheep herder, who probably lost all his communication skills and saw no one for the most part. Out of that circumstance of being a nobody, God then says, go to Pharaoh.
