When we compare them then we call one thing evil and the other good. Therefore people have called the devil all evil, to whom one should turn one's back, and God all goodness, to whom one should turn one's face. It was a convenient method to teach the people of those times. In reality God has no comparison. No doubt God can be compared if we make God good, as many do. But if we have a wider conception of God we cannot confine God to what we call goodness. What is our idea of goodness? It is very small. Perhaps it is good for us, but it is not something to judge God with.
