We take on the righteousness of Christ and are declared righteous by His account. We, because of our human nature , still have the curse of sin but it's penalty was nailed to the cross with Jesus. Our standing before God is fully righteous, not by our account, but buy Lord Jesus's .
So, does this mean that our righteousness is kept through our daily confessions to our Lord Jesus?
No, a believers declaration of righteousness is because of what Christ did in our stead, his act of substitution.
For instance, let's say I was a convicted murderer sentenced to death. Someone stepped forward and says, I know he is guilty as charged and has received righteous judgment. However, I love the accused so much that I offer my life for his, I will take his place.
The judge accepts the substitution, looks at me and says you are free to go. Not only has my debt been paid in full but the judge also orders my criminal history expunged
(removed from the records). My criminal history or slate has been "wiped clean", never again brought up or held against me.
Romans 5:6-9 " For when we were yet without strength, in due time Christ died for the ungodly. For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. Much more then, being now justified by his blood, we shall be saved from wrath through him."
Our righteousness is like filthy rags. We have the righteousness of Christ. We did not earn it and can do nothing to keep it. If He gives it to us we have it allways.
Confession is because your alive in Christ that you know you sin. You're conscience is alive bears witness. Psalm 66:18 states that if we cherish iniquity in our heart God will not hear our prayers. If we confess our sins to God, He who is faithful will forgive us of all our unrighteousness.
