This morning's gospel reading is about the man healed by Jesus of a "legion" of demons. Here's something I found on Lindy Black's site about that from the Interpreter's Bible:
The story of the Gerasene demoniac should now be interpreted so that it speaks a word of assurance and hope to those for whom every day is a battle with depression, fear, anxiety, or compulsive behavior. They will understand what would lead a person to say that his name is "mob" (GNB). With such a response, the man had acknowledged that he no longer had any individual identity. He had lost his name. He had lost his individuality. All that was left was a boiling struggle of conflicting forces. It was as though a Roman legion was at war within him.
