The good man out of his good treasure brings out good things, and the evil man out of his evil treasure brings out evil things.

Behold, one came to him and said, "Good teacher, what good thing shall I do, that I may have eternal life?"

He said to him, "Why do you call me good? No one is good but one, that is, God. But if you want to enter into life, keep the commandments."

"Either make the tree good, and its fruit good, or make the tree corrupt, and its fruit corrupt; for the tree is known by its fruit.

If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask him!

Even so, every good tree produces good fruit; but the corrupt tree produces evil fruit.

A good tree can't produce evil fruit, neither can a corrupt tree produce good fruit.
