Luke 6:43-45

43“For there is no good tree that produces rotten fruit, nor again does a rotten tree produce good fruit.

44Each tree comes to be known by its own fruit. For figs are not gleaned out of briars; neither are bunches of grapes gathered from thorn bushes.

45“Out of the good treasure of his heart the good man brings forth good, and out of evil the evil man brings forth evil. For from the overflow of the heart his mouth speaks.”
