"It is not because [the Christian] has had so little of Christ that he yearns for more. It is precisely because he has had so much of Christ that he is sure God intends him for the perfected experience. . . . Paul knew that what had entered him on the day of his conversion was life of the eternal order. He possessed it; it was there. Yet Holtzmann is perfectly right when he says that, 'Biblical religion in general, Pauline in particular, is a thirst for life.'"
