From a sermon on the Song of Songs by Saint Bernard:
Where can the weak find a place of firm security and peace, except in the wounds of the Savior? Indeed, the more secure is… my place there the more he can do to help me. The world rages, the flesh is heavy, and the devil lays his snares, but I do not fall, for my feet are planted on firm rock. I may have sinned gravely. My conscience would be distressed, but it would not be in turmoil, for I would recall the wounds of the Lord: he was wounded for our iniquities. What sin is there so deadly that it cannot be pardoned by the death of Christ? And so if I bear in mind this strong, effective remedy, I can never again be terrified by the malignancy of sin.
Surely the man who said: My sin is too great to merit pardon, was wrong. He was speaking as though he were not a member of Christ and had no share in his merits, so that he could claim them as his own […].
Through these sacred wounds we can see the secret of his heart, the great mystery of love, the sincerity of his mercy with which he visited us from on high. Where have your love, your mercy, your compassion shone out more luminously that in your wounds, sweet, gentle Lord of mercy? More mercy than this no one has than that he lay down his life for those who are doomed to death. My merit comes from his mercy.
