How does forgiveness work in Christianity?

In the Christian faith, forgiveness is intricately linked to God's grace and the atoning work of Christ. As stated in Ephesians 1:7, 'In him we have the forgiveness of sins in accordance with the riches of God's grace.' This forgiveness is not something that can be earned; rather, it flows freely from God's abundant grace that covers all sins of the believer—past, present, and future. The assurance of this forgiveness frees believers from guilt and condemnation, allowing them to experience the fullness of God's love and mercy. Understanding this concept encourages Christians to extend the same grace to others, reflecting the nature of God's forgiveness in their relationships.
