My mind can't even process what this experience might have been like for Moses. I wonder, though, why did God appear to Moses as an ever burning bush? He appeared to Abraham as a man in Genesis 18, and He spoke to Noah and Issac and Jacob in a "voice from heaven" kind of way. Why the dramatic appearance? Well, I do know that God does for each of us whatever we need to experience in order to understand. I guess Moses needed fire!
