Jesus Christ put it this way: "Either make the tree good and its fruit good, or else make the tree bad and its fruit bad; for a tree is known by its fruit" (Matthew 12:33).
UJesu uthi: "Ungenza isihlahla sibe sihle lesithelo saso sibe sihle, kumbe wenze isihlahla sibe sibi lesithelo saso sibe sibi, ngoba isihlahla saziwa ngezithelo zaso."  - UMathewu 12:33.
