Let me give you an illustration to discuss Grace a little more. Imagine that you have a house and you noticed a stain in one of the sides of the house.
As a ‘perfectionist’ will you break down the house because of the stain or will you just apply its paint to cover up/erase the stain? When you believe in Jesus, you are no longer a sinner, sin becomes like the stain on the wall of the house that the paint (blood of Jesus) has covered.
Sin is in the past, like the house that is completely built. It cannot surface again, because the house cannot be broken into pieces to be rebuilt because of a stain on the wall. 2 Samuel 12:4 made me understand how to see sin in the eyes of Grace.
Sin is a ‘traveller’ in the life of the believer; because the believer is human and can make mistakes. Sin has no resident in your life and cannot have dominion over it. A stay of a traveller/visitor is at the mercy of the person who is visited; that is not his abode. The law made man a sinner and Grace made man the righteousness of God in Christ. Before you call yourself a sinner or agree to be a sinner, ask yourself this question, ‘under what dispensation are mine living?’
It is either under the law in this dispensation of Grace or under Grace in this dispensation of Grace because the period of the Gospel (Grace) has succeeded that of the Law. If you are under Grace, sin does not make you a sinner, sin is a traveller/visitor, a stain in the wall that the blood has completely covered, once and for all. Is this clear enough?
