The parable of the unforgiving servant from Matthew 18 was today's Gospel reading at Mass. Jesus' message was that we must always forgive others. We already know that God will forgive us our trespasses as we forgive those who trespass against us. From this parable, we learn that once God has forgiven us, we'd better be forgiving like him. That is, if we expect to be forgiven by God, we should stop judging others – it's all about following his example. To not want to be like him is downright rebellion.
