There is no such thing as a good tree bearing worthless fruit, or, on the other hand, a worthless tree bearing good fruit.

It is by your bearing fruit plentifully, and so showing yourselves my disciples, that my Father is honored.

Bearing fruit and growing, as it does, through all the world, just as it did among you, from the very day that you heard of God's loving-kindness, and understood what that loving-kindness really is.
