I have another verse for you:
[1 John 1:9]
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
If we confess and not give any excuses, just admit and say "yes, I have sinned", He is faithful (He will not lie) and just (He has already paid the penalty of our sins on the Cross, it is FINISHED) to forgive us our sins (Hallelujah), and to cleanse us from all unrighteousness.
That is why, everytime we come before Him and confess and repent, we obtain His righteousness and we are cleansed.
