There is a moment of grace in most of the stories, or a moment where it
is offered, and usually rejected. Like when the Grandmother recognizes
the Misfit as one of her children (a child of God) and reaches out to
touch him. It’s the moment of grace for her anyway—a silly old woman—but
it leads him to shoot her. This moment of grace excites the devil to
frenzy.
