What does the Bible say about being completely forgiven?

Scripture affirms that all believers are completely forgiven of all their sins—past, present, and future—through the redeeming work of Christ on the cross. In Colossians 2:13, we read that God has forgiven all our trespasses, emphasizing that there is not a single sin that remains unforgiven for those who are united in Christ. This comprehensive forgiveness is part of our identity in Christ, underscoring that our standing before God is perfect due to His righteousness being imputed to us.
