On the devil's side the question seemed more complicated. But rereading the temptation story, it occurred to me that the one thing you cannot be without if you are serious about serving the devil is power. The temptation is to seek status through power. I think he is on to something. Love versus power.
Some interesting verses come to mind.
Which brings us to the Sermon on the Mount, our reading from Matthew. If we use these two poles, desire to love on the one end and desire for power on the other, it is an interesting way to think about the text. Beware of practicing your piety before others in order to be seen by them. Love or power. If we practice our faith so that others know what we are doing it could be that we are trying to influence them.
