Christian literature, to be accepted and approved by evangelical leaders of our times, must follow very closely the same train of thought, a kind of "party line" from which it is scarcely safe to depart. A half-century of this in America has made us smug and content. We imitate each other with slavish devotion. Our most strenuous efforts are put forth to try to say the same thing that everyone around us is saying--and yet to find an excuse for saying it, some little safe variation on the approved theme or, if no more, at least a new illustration.
