Luke 6:43-49

For there is no good tree which produces bad fruit, nor, on the other hand, a bad tree which produces good fruit. [Matt 7:16, 18] For each tree is known and identified by its own fruit. For figs are not picked from thorn bushes, nor is a cluster of grapes picked from a briar bush. The [intrinsically] good man produces what is good and honorable and moral out of the good treasure [stored] in his heart; and the [intrinsically] evil man produces what is wicked and depraved out of the evil [in his heart]; for his mouth speaks from the overflow of his heart. “Why do you call Me, ‘Lord, Lord,’ and do not practice what I tell you? Everyone who comes to Me and listens to My words and obeys them, I will show you whom he is like: [Matt 7:24-27] he is like a [far-sighted, practical, and sensible] man building a house, who dug deep and laid a foundation on the rock; and when a flood occurred, the torrent burst against that house and yet could not shake it, because it had been securely built and founded on the rock. But the one who has [merely] heard and has not practiced [what I say], is like a [foolish] man who built a house on the ground without any foundation, and the torrent burst against it; and it immediately collapsed, and the ruin of that house was great.”
