If you are sufficiently scrupulous not to have done any such thing recently, then ask whether there is any way in which you have lied to yourself. Or have kidded yourself. Or have been less than you could be—which is a self-betrayal. Be perfectly honest with yourself, and you will realize that you sin. If you do not realize it, then you are not perfectly honest with yourself, which is itself a sin. It is inescapable: we are all sinners.
