" Christian theism, to those who believe it, commends itself as fact, not theory, by the sheer multiplicity of its bearings. Were it a speculation, it would surely face a single field of enquiry: it would assign the cause of the world, or the principle of duty, or the aim of existence, or the means of spiritual regeneration. If an equal light falls from a single source in all these directions at once, that source must seem to have the richness of a reality, rather than the abstract poverty of an idea. "
