A good tree cannot bear bad fruit, nor can a bad tree bear 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 do not do the things that you wish.
Even so, every good tree bears good fruit, but a bad tree bears bad fruit.
Every tree that does not bear good fruit is cut down and thrown into the fire.
“For a good tree does not bear bad fruit, nor does a bad tree bear good fruit.
