You will be My apostles, My ambassadors, who will travel over the world to tell all the nations what I have told you.

You shall be the salt of humanity, and season it with wisdom.

You shall be the yeast which causes it to ferment.

To others I have said, Do the good work secretly; to you I say, Let your light shine forth as an example.

Be wily as the serpent, and let not hypocrites deceive you; be like clever money-changers, who accept only good coins and refuse the false.
