Forgiveness does not come naturally to human beings. It is expected that humans will defend themselves, lash out when attacked, hold grudges, and bite back. So, when human beings hear that they are forgiven, they may even be suspicious or skeptical. Jesus tells a parable that contrasts the forgiveness of God with our own unforgiving sinful nature. God forgives our huge debt. Who can comprehend such unexpected mercy? Certainly not unmerciful servants, who refuse to forgive small debts. Have mercy on us, Lord, and teach us to forgive like you!
