In any great forest you will find many huge trees. They tower above other trees and appear to be the very picture of strength and maturity. However, loggers will sometimes not even bother to cut down these huge trees. At first one wonders, “Why leave them? After all, a tree that big must contain twice or thrice the amount of lumber as a smaller tree.”

The reason is simple. Huge trees are often rotten on the inside. They are the hollow trees that children’s picture books show raccoons living in. And they are the trees that are often blown over in a strong windstorm because, while they appear to be the picture of strength, in fact their hollowness makes them weak.

This is the essence of hypocrisy—appearing strong on the outside but hollow and rotten on the inside.
