God and Satan are just the polarities within which to choose how to live our lives. We have thoughts from both extremities and without one, the other could not exist. It would completely change life for humanity.
The power of God and Satan is divided up by us, not by them. I hope Satan never goes away but that we make more informed decisions based on greater understanding.
Satan is not to be hated. Satan is to be accepted, heard and seen by all. Why be afraid when all he does is make suggestions to each of us? It's more reasonable to be afraid of a god who has such high expectations of us, OR have I gotten them mixed up?
