In Matthew 18v21–35, Jesus teaches that forgiveness is first a matter of the heart, flowing out of the abundant mercy and grace God has already shown us in Christ. Because God forgives us completely—legally, lovingly, and compassionately—His people are called to release anger, resist bitterness, and extend forgiveness instead of vengeance. True forgiveness is the costly, daily choice to absorb wrongs in love so that others may be freed, relationships may be restored, and the Kingdom of God may come.
