Are grapes gathered from thornbushes, or figs from thistles? Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. So then, by their fruit you will recognize them.

                                                                                           -Jesus, Gospel of Matthew

O MY SERVANTS! Ye are the trees of My garden; ye must give forth goodly and wondrous fruits, that ye yourselves and others may profit therefrom. Thus it is incumbent on every one to engage in crafts and professions, for therein lies the secret of wealth, O men of understanding! For results depend upon means, and the grace of God shall be all-sufficient unto you. Trees that yield no fruit have been and will ever be for the fire.
