43 For there is no good (healthy) tree that bears decayed (worthless, stale) fruit, nor on the other hand does a decayed (worthless, sickly) tree bear good fruit.
44 For each tree is known and identified by its own fruit; for figs are not gathered from thornbushes, nor is a cluster of grapes picked from a bramblebush.
45 The upright (honorable, intrinsically good) man out of the good treasure [stored] in his heart produces what is upright (honorable and intrinsically good), and the evil man out of the evil storehouse brings forth that which is depraved (wicked and intrinsically evil); for out of the abundance (overflow) of the heart his mouth speaks.
46 Why do you call Me, Lord, Lord, and do not [practice] what I tell you?
47 For everyone who comes to Me and listens to My words [in order to heed their teaching] and does them, I will show you what he is like:
48 He is like a man building a house, who dug and went down deep and laid a foundation upon the rock; and when a flood arose, the torrent broke against that house and could not shake or move it, because it had been securely built or founded on a rock.
49 But he who merely hears and does not practice doing My words is like a man who built a house on the ground without a foundation, against which the torrent burst, and immediately it collapsed and fell, and the breaking and ruin of that house was great.
