If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
As far as the east is from the west, so far has he removed our transgressions from us.
Let the wicked forsake his way and the evil man his thoughts. Let him turn to the Lord, and he will have mercy on him, and to our God, for he will freely pardon.
How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
1 John 1:8-1
I will cleanse them from all the sin they have committed against me and will forgive all their sins of rebellion against me
He was delivered over to death for our sins and was raised to life for our justification.
For the Lord your God is gracious and compassionate, He will not turn his face from you if you return unto him.
2 Chronicles 30:9
For I will forgive their wickedness and remember their sins no more.
Therefore if anyone is in Christ he is a new creation; the old has gone, the new has come!
2 Corinthians 5:17
