In the Our Father we say: “Forgive us our debts as we forgive our debtors.” This is an equation. If you are not capable of forgiveness, how can God forgive you? The Lord wants to forgive you, but he cannot if you keep your heart closed and mercy cannot enter. One might object: “Father, I forgive, but I cannot forget that awful thing that he did to me….” The answer is to ask the Lord to help you forget. One must forgive as God forgives, and God forgives the maximum.”
— Pope Francis, as quoted in the book The Hope of Lent: Daily Reflections from Pope Francis by Diane M. Houdek
