In the fifth petition of the Lord’s Prayer, we ask God to forgive us our debts as we forgive our debtors. Does that make our forgiving others the condition of God’s forgiving us? In Part 2 of our series on repentance and forgiveness, Dr. J. Mark Beach examines the question with Calvin, the Heidelberg Catechism, and the parable of the unmerciful servant. Dr. Beach shows why the Reformers refused to make our forgiveness of others the ground of God’s, and what it does demonstrate. Dr. Beach also takes up a hard pastoral question: what do we owe a brother who has wronged us and shows no sorrow?
