Luke 6:43-46 - The Sermon On The Plain: Trees And Their Fruit
43 "A good tree doesn't produce rotten fruit, and a rotten tree doesn't produce good fruit, 44 because every tree is known by its own fruit. People don't gather figs from thorny plants or pick grapes from a thorn bush. 45 A good person produces good from the good treasure of his heart, and an evil person produces evil from an evil treasure, because the mouth speaks from the overflow of the heart."
46 "Why do you keep calling me "Lord, Lord,' but don't do what I tell you?
