Wasn't that done at the cross, and all our past ,present and future sins were forgiven then?
Also because Christ became righteous for us we are just ,righteous and holy now.
Ro:5:19: For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.

So now we are the righteousness of God according to the scriptures and not a sinner saved by grace.
