Everybody knows, people are born "graven in stone", and without any possibility of change or a renewing of the mind.
I guess that is why new movements never gather converts !
Perhaps Stalin, Hitler, Mao, Confucius, Buddha, Luther, Billy Sunday and Billy Graham never changed anyone's mind.
Then too, let us consider...Did Peter, Paul, Mark or John convince anyone to change their ways and their mind?
I won't suggest Jesus, since God can change the universe if He wishes..
