I like at the end of this video when he talks about people trying to define THEIR truth as THE truth. It goes back to relativism, the fact that what is true for you may not be true for everyone else.
It makes me think of John the Baptist. He had a pretty wild lifestyle; it was intense. Could you imagine if he spent all of his time trying to convert people to his lifestyle? What if he saw it as more than his calling - it had to be everyone else's too? He might have missed Jesus if he were to have taken that path.
