LUK 6:44

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.
