Nothing makes us so like God as our readiness to forgive the wicked and wrongdoer. For it is God who has made “the sun to shine on the evil and on the good.”
For this same reason again in every one of the clauses Jesus commands us to make our prayers together in one voice, saying, “Our Father,” and “thy will be done in earth as it is in heaven,” and “give us the bread, and forgive us our debts,” and “lead us not into temptation,” and “deliver us.” So everywhere he is teaching us to use this plural word that we may not retain so much as a vestige of resentment against our neighbor.
How great a reproof then must they deserve, who, after all this, still do not forgive and even ask God’s vengeance on their enemies. In doing so, they diametrically transgress this command. Meanwhile Christ is seeking in every way possible to hinder our conflicts with one another. For since love is the root of all that is good, by removing from all quarters whatever mars it he brings us together and cements us to each other. For there is not one, not a single one, whether father or mother or friend, who loves us as much as the God who created us.
St. John Chrysostom
