As I have mentioned, the Pass time of God is to expose us.
Lets say that I am talking about fighting corruption and giving fiery speeches on that. But, I engage in corruption myself. I go to great length and have very good and foolproof mechanism of collecting my bribes, ensuring that no one even know that I collect it.

I talk to people in public very nicely and politely. But to my own employees or to my wife, I am talk arrogantly. If I am getting exposed in public, with such a bad temperament which is not I am projecting outside, then it will be another embarrassing situation.
So Its hard, but is not impossible to " walk the talk ". No one is perfect, but we can strive.
