a man can only guess, and i am only guessing but.....
they re all pointless, as written someplace, everything apart from faith is sin, that really brodens the sinfulness of sin, it is all just a tastefull, sexy, marrrage of pointlessness, fasehood, passing by and leaving you empty handed sin is a vegue english term, with a bigger sence than just the act itself, a lie or to be false or pretending, have sin within them, and are sin themselves, but to just use "sin" to call something a sin is a misuse of a much bigger context, and scope of the term. "that is a sin" used by a fool makes any inteligent man cringe, possably with vomiting reflexes
sex is not pointless or sin in the benifishal contexts of orderly faithfull living, eating is not a sin if done in the faithfull manner, cocacola is not a sin if done likewise,
to live unfaithfully is to be entirely immerced in it and there is nouthing you can be doing that is not sin, at least by HIS definition, so now being a slave to sin, one must find escape, ill leave that serch up to you.
