“You were dead because of your sins and because your sinful nature was not yet cut away. Then God made you alive with Christ, for he forgave all our sins. He canceled the record of the charges against us and took it away by nailing it to the cross.”
Colossians 2:13-14 NLT

If the record of your charges have been cancelled why are you reminding yourself of your past sins?
Embrace the freedom you’ve now inherited as a result of Jesus’ sacrifice on the cross.
He has set you free from the law of sin and death.
He has reconciled you to the Father.
