Devil, cf. Satan
G. Lewis, Demon Possession, ed. J. Montgomery
Two 6 year olds struggled with the problem of the existence of the devil. One boy said, "Oh, there isn't any devil." The other, rather upset, said, "What do you mean, there isn't any devil? It talks about him all the way through the Bible!" the first replied, "Oh that's not true, you know. It's just like Santa Claus, the devil turns out to be your dad."
