My kingdom isn’t in the world. Sc. 87, John 18:36

Two things to consider:

  1. When we fight with men, as we sometimes must, we are in this world.
  2. When we fight with the devil, as we sometimes may have to, we are not fighting with men.

Get out of my way, Satan. Sc. 53, Matthew 16:23, Mark 8:33

Yet Peter is a saint, and Satan is a devil.
