A good tree can't produce bad fruit, and a bad tree can't produce good fruit.
So every good tree produces good fruit, while a bad tree produces bad fruit.
Every tree that doesn't produce good fruit is chopped down and thrown into the fire.
A good tree doesn't produce bad fruit, and a bad tree doesn't produce good fruit.
For the desires of the sinful nature are opposed to the Spirit, and the desires of the Spirit are opposed to the sinful nature. They fight one another, so you don't do what you want to do.
