C. S. Lewis noted at the start of The Screwtape Letters that: "There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight." When it comes to demons people either attribute way too much to them so that they think that a demon lurks behind every stone and they live in constant fear, or they never give any thought to demons and act like they do not exist. Mark does not allow us to either ignore the reality of demons or to give us any reason to live in fear of them because Jesus's power is over the natural and supernatural realms of the created order. All are to fear His Holy name so that "at the name of Jesus, every knee shall bow and every tongue confess that Jesus is Lord".
