It is not possible for a good tree to give bad fruit, and a bad tree will not give good fruit.
Even so, every good tree gives good fruit; but the bad tree gives evil fruit.
Every tree which does not give good fruit is cut down and put in the fire.
For no good tree gives bad fruit, and no bad tree gives good fruit.
For the flesh has desires against the Spirit, and the Spirit against the flesh; because these are opposite the one to the other; so that you may not do the things which you have a mind to do.
