Many of us probably have a room in our house where we keep all our junk—an office, the garage, etc. Since we already see that room as dirty, we let it continue being dirty and even add more junk to it. A lot of us, if we are are honest, think we are dirty. It's easier to believe we are unclean, than it is to believe we are righteous. We aren't partially righteous in Jesus and then we complete it through our own righteousness. We are fully righteous through our faith in Christ's finished work on the cross. When you truly see how clean you are in Christ, you won't so easily add sin to your life. Don't call unclean what Jesus calls clean.
