In ancient times many have tried to help the imagination of those who sought goodness by teaching them belief in Satan, saying that God is all goodness and Satan all badness. This was in order to explain to those who could not understand where badness came from. In reality badness is only the shadow of goodness; and as a shadow is non-existent so evil is nonexistent. Good is always going forward; what is left behind is less good, and what is gained on the journey forward is more good. But when we compare things then we call one thing evil and the other good. Therefore people have called the devil, on whom we should turn our back, all evil; and God, to whom we should give our faith, all goodness. It was simply a method of teaching the people of ancient times. In reality God is beyond comparison, though of course we compare God with something when we call Him good, as many do. What is our own goodness? It is very small; it is not something to judge God by.
