It isn’t good for us to dwell on our past sins. God is merciful, and all he wants of us is that we put the past behind us, showering ourselves in his kindness, as we make good fresh starts.
There is one time, however, when we should remind ourselves of our past failings. That is when we are inclined to criticize another for the faults of which we have been guilty.
That is what Jesus is telling us in today’s parable. That is the bargain we make when we recite the Lord’s Prayer, saying, ”Father, forgive us our trespasses as we forgive those who trespass against us.”
