Noble deeds that are concealed are most esteemed.

It is certain that those who have the living faith in their hearts see at once that all existence is none other than the work of the God whom they adore.

Generally we are occupied either with the miseries which now we feel, or with those which threaten; and even when we see ourselves sufficiently secure from the approach of either, still fretfulness, though unwarranted by either present or expected affliction, fails not to spring up from the deep recesses of the heart, where its roots naturally grow, and to fill the soul with its poison.

Brave deeds are wasted when hidden.
