Justified can seem like just as though I never sinned. But that's like a english word trick. It could seem that way for your sins not to be considered against you. But there is something to the fact that a woman washed Jesus feet with tears knowing she had sinned and been forgiven and could have new life. That Jesus said knowing you were forgiven much would make you love Him more. Forgetting you are forgiven could have a bad effect. Its not bringing back your sin all the time. Its knowing you were forgiven of them all and not forgetting. Where most of us were not prostitutes we still need to remember that we are forgiven very much daily and that Grace is what justified us to be just as though we are righteous.
