Luke 6:43-49 (ESV)
A Tree and Its Fruit
43 “For no good tree bears bad fruit, nor again does a bad tree bear good fruit, 44 for each tree is known by its own fruit. For figs are not gathered from thornbushes, nor are grapes picked from a bramble bush. 45 The good person out of the good treasure of his heart produces good, and the evil person out of his evil treasure produces evil, for out of the abundance of the heart his mouth speaks.
Build Your House on the Rock
46 “Why do you call me ‘Lord, Lord,’ and not do what I tell you? 47 Everyone who comes to me and hears my words and does them, I will show you what he is like: 48 he is like a man building a house, who dug deep and laid the foundation on the rock. And when a flood arose, the stream broke against that house and could not shake it, because it had been well built.  49 But the one who hears and does not do them is like a man who built a house on the ground without a foundation. When the stream broke against it, immediately it fell, and the ruin of that house was great.”
