1 Peter 1:3

Blessed be the God and Father of our Lord Jesus Christ, who according to His abundant and boundless mercy has caused us to be born again (that is, to be reborn from above-spiritually transformed, renewed, and set apart for His purpose) to an ever-living hope and confident assurance through the resurrection of Jesus Christ from the dead.

When we were born again, God washed our sins away and hid them with Jesus Christ. The devil tries to use sin to guilt and shame, which separates a Christian from God. When we realize that we don’t have to accept the devil’s condemnation and just repent to God for our wrongdoings. We take away the power the devil has over us and move forward with God.
