Luke 6:43-45

“A good tree doesn’t produce bad fruit; on the other hand, a bad tree doesn’t produce good fruit. For each tree is known by its own fruit. Figs aren’t gathered from thornbushes, or grapes picked from a bramble bush. A good person produces good out of the good stored up in his heart. An evil person produces evil out of the evil stored up in his heart, for his mouth speaks from the overflow of the heart.
