Commentary by Dr. Whitesel: Here is research published in the The Association of Religious Data Archives, which confirms CS Lewis quote, “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 un- healthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight” (C.S. Lewis. The Screwtape Letters, HarperSanFrancisco, ©1942, Harper edition 2001, p. ix.)

… Belief in the existence of powerful supernatural evil beings was one of the strongest predictors of poor mental health in young adults, according to a new study by Purdue University researchers.
