Fire that does not consume

I was recently reminded of the story of Moses and the burning bush. What made the fire stand out to Moses was that it burned without consuming the bush. In other words, this flame defied the laws of physics. It was feeding on something beyond early understanding.

Moses was confused, because he had no reference for a fire that does not consume. But isn't our own life energy a similar miracle?

Sure; I eat food, drink liquids, and rest. But where do all the dimensions of my life force and energy come from?

Where does your fire burn without consuming?
