[[1. We cannot rid ourselves of sin. To uproot sin and the evil that is so imbedded in our sinning can be done only by divine power, for it is impossible and outside man’s competence to uproot sin.]]
You can’t uproot it totally of course, but you CAN put a serious damper on it by ENFORCING laws against sin- or take it a step further, there was little open sin in biblical times (not that anyone is suggesting we go back to such harsh cultural laws)- and people were actually ashamed of sin back I n those days because they KNEW society looked down on such shameful acts- Sure, there was still sin, but it wasn’t nearly as public and brazen and shameless as it is today- the only places it was, was in societies back then that had no morals- much like today’s society
Even then, it can be touch-and-go for the committed believer. The old nature has to be starved.
