Forgive us, as we forgive those who trespass against us.

How much the Lord values it when we love one another! After all, the good Jesus could have mentioned other reasons and said: "Forgive us, Lord, because we do great penance, because we pray a lot, because we fast, because we have left everything for you and love you immensely." He did not even say: "Forgive us because we are willing to sacrifice our lives for you" and similar things, but only: "Forgive us, as we also forgive."

(Teresa of Jesus, The Way of Perfection XXXVI,7)
