For the redemption of his soul is costly, and never can payment suffice,
- Psalm 49:8
What can suffice the man whom virtue and felicity do not suffice? For surely virtue comprehends all things we need do, felicity all things we need wish for.
- St. Augustine
What does it cost us to say: "My God help me! Have mercy on me!" Is there anything easier than this? And this little will suffice to save us if we be diligent in doing it.
