"Forgive us our sins as we forgive those who sin against us." Theologian Stanley Hauerwas says this petition of the Lord's Prayer is the hardest one to pray. Some of us have trouble acknowledging we need forgiveness from God; others of us find it hard to forgive other people who have hurt us. But both are essential, says Jesus, to live in a way that pleases God. We need God's Spirit to help us do both.
