Have confidence in the compassion of our Creator. Reflect well on what you are now doing, and keep before you the things you have done. Lift up your eyes to the overflowing compassion of heaven, and while He waits for you, draw near in tears to our merciful Judge. Having before your mind that He is a Just Judge, do not take your sins lightly; and having also in mind that He is compassionate, do not despair. The God-Man gives man confidence before God.
Pope Gregory IYou cannot acquire the gift of peace if by your anger you destroy the peace of the Lord.
Pope Gregory IThere is more joy in heaven over a converted sinner than over a righteous person standing firm. A leader in battle has more love for a soldier who returns after fleeing, and who valiantly pursues the enemy, than for one who never turned back, but who never acted valiantly either. A farmer has greater love for land which bears fruitfully, after he has cleared it of thorns, than for land which never had thorns but which never yielded a fruitful harvest.
Pope Gregory I
