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 does not bring forth good fruit is cut down, and thrown into the fire.
For a good tree does not bring 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 to one another: so that you cannot do the things that you would.
