A few years ago, Roche Pharmaceuticals began an aggressive advertising campaign promoting its prescription treatment for Hepatitis C. The ads featured a close-up of an individual with a badly-marred face, and a caption that read: "If Hep C attacked your face instead of your liver, you'd do something about it."

Most Christians believe that sin is harmful, and that it has negative consequences. Yet it is still very difficult for that knowledge to change our behavior. Maybe we should ask ourselves: What if sin attacked my face?
