When people get hurt, they won't hesitate to have shrapnel and debris removed for their wounds. Sin is debris in the soul, and like the physical type, if left untreated it can fester and spread infection. God reminds us, "for sin will not rule over you, for you are not under law, but under grace." (Romans 6:14)
Let's live up to that and scrub out the sin.
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
