43 "People are like trees [MET]. Healthy trees do not bear bad fruit (OR, bear only good fruit), and unhealthy trees do not bear good fruit. 44 Just like you can tell if a tree is good or bad by looking at its fruit, you can tell which people are good and which are bad by looking at the way they conduct their lives. For example, because thornbushes cannot produce figs, no one can pick figs from thornbushes. And since bramble bushes cannot produce grapes, no one can pick grapes from bramble bushes. 45 Similarly, good people will conduct their lives in a good way because they think a lot of good things, and evil people will live in an evil way because they think a lot of evil things. The basic principle is that people speak and act according to all that they think."
