Some of the most refreshing people to spend time with are converted murderers and recovered terminal patients. Someone who used to kill people has no illusions about what a nice guy he is, or what he would be like without God. Someone who was given six months to live has no illusions that he will live forever, or where his life comes from. Neither kind of person wastes as much time on themselves as the rest of us who haven’t yet come to the end of ourselves.
