43 A good tree cannot produce bad fruit, and a bad tree cannot produce good fruit.
44 You can tell what a tree is like by the fruit it produces. You cannot pick figs or grapes from thorn bushes.
45 Good people do good things because of the good in their hearts. Bad people do bad things because of the evil in their hearts. Your words show what is in your heart.
46 Why do you keep on saying that I am your Lord, when you refuse to do what I say?
47 Anyone who comes and listens to me and obeys me
48 is like someone who dug down deep and built a house on solid rock. When the flood came and the river rushed against the house, it was built so well that it didn't even shake.
49 But anyone who hears what I say and doesn't obey me is like someone whose house wasn't built on solid rock. As soon as the river rushed against that house, it was smashed to pieces!
