"...each tree is known by its own fruit." -Jesus from Luke 6:44
I was told this story:
A man and his family loved Golden Delicious Apples, and he owned some land. One day his wife asked him if he would plant some Golden Delicious Apple trees. The man was excited about the opportunity to own his own Golden Delicious trees. He went to a farmer and got some seeds for Golden Delicious trees. He planted those seeds and the trees grew.
About two years later the trees were starting to produce fruit. The man was proud, but his wife was a little concerned because she had gone out to the tree and noticed there was something wrong with the fruit. Upon further investigation she realized they weren't producing Golden Delicious apples... they were producing peaches.
