True but I have heard of a man who was supposedly approached by a demnic spirit who said " I am Jesus" he replied "but what of Mashaich Ben El Shaddai" and the entity fled screaming in pure terror, knowing what that name mweant to it and what it now means to it. There is power in the name and the blood. When saw we thee naked and clothed thee or hungry and fed thee? Youknow the rest. Some will never get it til too late.
