The lesson from today's Gospel from Matthew 18 is very clear. We must be merciful to others as our heavenly Father is merciful to us, and always forgive those who have sinned against us. This is following the example of Christ the Lord and is what must distinguish his followers. Whatever we do to others, we must let love reign, overriding all other negative feelings. If we want God to be forgiving to us always, then we must likewise be forgiving always.
