sin From Louis... As an outsider to all religion, I don't really understand "sin" either. According to an encyclopedia, the word "sin" comes from the root word "sunder", as in "put asunder" or "break apart". Thus "to sin" means CHOOSING to break apart from a pre-established set of rules - a universal standard of behaviour, if there IS such a thing. It means being AWARE OF and COMMITING TO such a standard, except when it comes in conflict with something YOU want to do. Then you have some choices .... DON'T do what you want and stay "righteous". DO what you want, then hope to get away with it by being "forgiven". DO what you want and blame it on "the Devil". Does that clear up anything ?
