God has forgiven the sins of those who have received the Lord Jesus Christ. Even before Jesus was manifest on earth God had promised this. Below are a few promises reminding you of what God has done with your sins.
I, even I, am the one who wipes out your transgressions for My own sake, and I will not remember your sins.
Let the wicked forsake his way and the unrighteous man his thoughts; and let him return to the LORD, and He will have compassion on him, and to our God, for He will abundantly pardon.
I acknowledged my sin to You, and my iniquity I did not hide; I said, 'I will confess my transgressions to the LORD'; and You forgave the guilt of my sin.
If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.
1 John 1:9
How blessed is he whose transgression is forgiven, whose sin is covered!
Then I heard a loud voice in heaven, saying, 'Now the salvation, and the power, and the kingdom of our God and the authority of His Christ have come, for the accuser of our brethren has been thrown down, he who accuses them before our God day and night. And they overcame him because of the blood of the Lamb and because of the word of their testimony, and they did not love their life even when faced with death.'
Revelation 12:10, 11
Straightening up, Jesus said to her, 'Woman, where are they? Did no one condemn you?' She said, 'No one, Lord.' And Jesus said, 'I do not condemn you, either. Go. From now on sin no more.'
John 8:10, 11
They will not teach again, each man his neighbor and each man his brother, saying, 'Know the LORD,' for they will all know Me, from the least of them to the greatest of them, declares the LORD, 'for I will forgive their iniquity, and their sin I will remember no more.'
Let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
For if you return to the LORD, your brothers and your sons will find compassion before those who led them captive and will return to this land. For the LORD your God is gracious and compassionate, and will not turn His face away from you if you return to Him.
2 Chronicles 30:9
Since God has forgiven your sins don't allow satan to torment you with tham again.
