The best way to discover our duty is to study the divinely inspired Scriptures, for in them we find both instructions about conduct and the lives of blessed men, delivered in writing. They are laid before us like living images of the godly life for the imitation of their good works. When we devote ourselves to the imitation of what is offered there, we find the appropriate medicine for whatever deficiency or illness we feel we have, as from a pharmacy.
