He's a con artist preying on the feeble minded, just like every other religious leader. It is nice that his tone and message are less psychologically crippling than those of most of his colleagues in the mental abuse field, but, at the end of the day, he's no less of a trickster.
Excessive hyperbole.
Granted, like politicians, religious leaders do have more than their share of con artists, but most religious leaders (and most politicians) are sincere about their beliefs.
And with the exception of L. Ron Hubbard, religious founders are also sincere.
