Luke 6:43-46 - The Sermon On The Plain: Trees And Their Fruit
43 For there is no good tree that brings forth rotten fruit; nor again a rotten tree that brings forth good fruit. 44 For each tree is known by its own fruit. For people don't gather figs from thorns, nor do they gather grapes from a bramble bush. 45 The good man out of the good treasure of his heart brings out that which is good, and the evil man out of the evil treasure of his heart brings out that which is evil, for out of the abundance of the heart, his mouth speaks.
46 "Why do you call me, 'Lord, Lord,' and don't do the things which I say?
