"That's your whole answer, son.  If what you say is true - and I'm not judging; I'm asking, you're answering - then that's all the competition you need... and a fairly one-sided race, too.  If one tenth of one percent of the population is capable of getting the news, then all you have to do is show them - and in a matter of some generations all the stupid ones will die out and those with your discipline will inherit the Earth.  Whenever that is - a thousand years from now, or ten thousand - will be plenty soon enough to worry about whether some new hurdle is necessary to make them jump higher.  But don't go getting faint-hearted because only a handful have turned into angels overnight.  Personally, I never expected any of them to manage it.  I simply thought you were making a damn fool of yourself by pretending to be a preacher."
