Simply said, when we put our faith in Christ, God no longer counts our sin against us. Paul explains to us in Colossians 2:12-15 that Jesus raised us from the dead, crossed out our debts, and disarmed the demons. Our sin was an eternal debt to God. However Jesus — perfect and eternal — paid 100% of our eternal debt — past, present, and future — through dying on the cross and being raised to life. He nailed our sins to that cross and covered us in His blood. Christ used Satan's momentum against him. Through Christ's death, He brought us forgiveness and life. It is finished — our debt has been paid!
