(Many religions, from Judaism to Zoroastrianism, use light and fire as symbols for the presence of God, perhaps because light, like God, cannot be seen but permits us to see everything there is, perhaps because fire liberates the energy hidden in a log of wood or a lump of coal just as God liberates the potential energy to do good things that is hidden in every human being, just as God will be the fire that burns within Moses, enabling him to do the great things he will go on to do, but not consuming him in the process.)
~ Harold S. Kushner
