There is no antagonism between the physical and the spiritual. The physical world is to man a medium through which phases of the spiritual are reached. The only antagonism there can be is that which arises by an attempt to use the material without regard for its full spiritual contents or inside. Were not the physical universe a sacrament it would be a phantasm. If man divorces the inside from the outside with a view to gratifying his physical senses he abdicates his character as a man to become an animal; if to feed anything less than his entire selfhood, he presents the spectacle of arrested development. The bodily senses alone can get at the full content, the deep inside of nothing, no matter how pronounced its objectivity, “The truly real is a thing that has an inside.”[3] The more pronounced or attractive the external substance and form of a material object and the closer we are to it, the greater the difficulty for the average character to gain cognition of its spiritual essence. “How hardly shall they that have riches enter into the Kingdom of God.”[4] Even those who place an undue valuation upon the material, whether possessed of wealth or not, have a like difficulty in penetrating into the internal realm which lies beneath and around as well as above and within the external.[5] It is absurd for men to expect to sense the spiritual except with spiritual faculties. The physical world is perceived by a sensory apparatus of the same substance as that of the physical world; the spiritual world is perceived by a sensory apparatus of the same substance as that of the spiritual world. There must be an inherent affinity between the thing apprehended and the organ apprehending. Now the natural man receiveth not the things of the Spirit of God; for they are foolishness unto him; and he cannot know them because they are spiritually proved.[6]
