Thematic Bible: Tree and its fruit

For no good tree gives bad fruit, and no bad tree gives good fruit. For every tree is judged by its fruit. Men do not get figs from thorns, or grapes from blackberry plants. The good man, out of the good store of his heart, gives good things; and the evil man, out of his evil store, gives evil: for out of the full store of the heart come the words of the mouth.
