Luke 6:43-46 - The Sermon On The Plain: Trees And Their Fruit
43 There is no such thing as a good tree bearing worthless fruit, or, on the other hand, a worthless tree bearing good fruit. 44 For every tree is known by its own fruit. People do not gather figs off thorn bushes, nor pick a bunch of grapes off a bramble. 45 A good man, from the good stores of his heart, brings out what is good; while a bad man, from his bad stores, brings out what is bad. For what fills a man's heart will rise to his lips.
46 Why do you call me 'Master! Master!' and yet fail to do what I tell you?
