The intent of the plan of happiness is not for us to sin and then to be forgiven; it is for us become the kind of people who don’t commit those sins any more. Our sins can be washed away in the legalistic sense that the slate is wiped clean and those sins are not held against us any more (justification). More importantly, they can be washed away in the sense that we overcome them and do not commit them any more (sanctification).
