A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
Even so every good tree brings forth good fruit; but a corrupt tree brings forth evil fruit.
Every tree that brings not forth good fruit is hewn down, and cast into the fire.
For a good tree brings not forth corrupt fruit; neither does a corrupt tree bring forth good fruit.
For the flesh lusts against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that you cannot do the things that you would.
