The Good Witch says to Oz: I always knew you had it in you.

Oz asks: greatness?

The Good Witch says: no, goodness.

In his quest for greatness (a cloak for his rotten core), he finds a Good Witch who knows he is a liar and a conman and a fake. And yet she loves him. When she tells him he is good, he says to her: so I fooled you. He does not allow for the possibility that he is good with his flaws, he thinks he won't penetrate the force field that allows only good hearts to pass because he believes he actually IS bad. She loves him not for the illusion of greatness but for the honest goodness inside.

The same lesson taught to us in story after story. We don't understand it until we do, then we see that everyone has been talking about it all along only we didn't understand the language.
