This all started when the Pharisees saw the Disciples eating food with unwashed hands and were offended.  Jesus gave the crowd a quick Anatomy/Physiology lesson when He concluded that all food (whether clean or unclean) goes into a man’s stomach, not his heart.  He then instructed the crowd by saying, “Nothing outside a man can make him unclean by going into him.  Rather, it is what comes out of a man that makes him unclean.” (Mark 7:15)    I’ve heard it said,  if you shake a man, you’ll see what’s in his heart.  For it’s deep within our heart that all wickedness abides.
