What I mean by "sin" is doing that which is against the imitation of Jesus. The word Christian means "Jesus imitator" or "follower." If one hears what Jesus requires of his followers and does the opposite, that is sin or, in the Greek, "missing the mark" of Jesus's model.

When I speak of Ron Paul, I am not referring to his character here, but rather his stated platform for what he would do if hired to be the president of the United States. Ron Paul demonstrates excellent character in being married to one woman for 59 years and being the father of five children who demonstrate imitation of their father's love for liberty and medical practice. But I cannot truly speak for the character of candidates who have sought the presidency in my lifetime. I can only judge the ethics of their stated platform of what they would do if elected president. Every one of them fails to hit the mark of faithful imitation of Jesus except Ron Paul.
