Modern men have faith in machines, in material well-being, in the substantiality of all that seems obvious to common sense; this is a petty faith, the faith of petty men. The Christian has faith in God and the world to come, in the insubstantiality of all that is obvious, in the passing of this world and the coming of the new, transfigured world; if there is a faith worthy of men, it is surely this.
