A: What is God? You don't know what God is. God cannot be a human being. God is Light; God is power. God cannot talk. Electricity cannot give light. Only the bulb gives light, but electricity has to be put through the wire for the bulb to give light. It's power. Power cannot do anything; it has to be put through a medium. Yes?
