Do you think it is a vain hope that one day man will find joy in noble deeds of light and mercy, rather than in the coarse pleasures he indulges in today -- gluttony, fornication, ostentation, boasting, and envious vying with his neighbor? I am certain this is not a vain hope and that the day will come soon.
