Moses’ questions make a subtle shift moving into chapter 4. This is no longer humility or sincere questions. He is beginning to make excuses. And it ought to absolutely shock us, that the God of the universe, the creator of all, the Great I AM, does not just silence Moses and cut him off. The flames of the burning bush don’t just turn into a white hot blow torch and incinerate him. The Lord actually listens to Moses’ excuses and He answers them.
