Three great forces
Anger really means impatience (as opposed to the righteous anger that is desirable in many circumstances). Impatience makes us get ahead of ourselves, reaching out for something in the future and not really being content with where we are, here and now.
Lust extends much wider than the sexual sphere, and essentially means attachment to something that is not present, or is not the appropriate thing right now.
And one by-product of laziness, of being victimized by the noonday devil, is sadness — not the genuine sorrow of compassion, but the lifeless ennui of never really being involved in the present, with what’s happening.
If you would like another contemporary interpretation of the idea of spiritual warfare, there is C.S. Lewis' The Screwtape Letters , in which he translates the tradition with great wit and insight into a modern idiom. It’s all about struggling with the forces that are all around us in the world and within us and that distract us from being really unified, in one piece.
