Vainglory speaks thus: Yes, do all the good you can, but publish it, so that the world may regard you as a man of great virtue and treat you with consideration and respect. Fear of God answers: It is great folly to devote to the acquisition of temporal renown that which can obtain for you eternal glory. Endeavor to hide your good actions, and if they appear in spite of your efforts to conceal them it will not be accounted vanity in you when you have no desire to display them.
