As one theologian has noted, the first generation is characterized by a true and living zeal. The second generation seeks to consolidate the gains of the first, but does so by means of legalistic and oppressive rules. The third generation goes liberal, out of a reaction to the stupidity of a blind conservatism. The fourth generation goes apostate, and it is time for a revival. God specializes in bringing great spiritual vigor out of bodies that are as good as dead.
