A good tree cannot bring forth evil fruits, nor 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; lest whatever you may will, these things you do.
