There lies a something at the back of the correspondences of the spiritual organism--just as there lies a something at the back of the natural correspondence. To say that Life is a correspondence is only to express the partial truth. There is something behind. Life manifests itself in correspondences. But what determines them? The organism exhibits a variety of correspondences. What organizes them? As in the natural, so in the spiritual, there is a Principle of Life. We cannot get rid of that term. However clumsy, however provisional, however much a mere cloak for ignorance, Science as yet is unable to dispense with the idea of a Principle of Life. We must work with the word till we get a better. Now that which determines the correspondence of the spiritual organism is a Principle of Spiritual Life. It is a new and Divine Possession. He that hath the Son hath Life; conversely, he that hath Life hath the Son. And this indicates at once the quality and the quantity of the correspondence which is to bridge the grave. He that hath Life hath _the Son_. He possesses the Spirit of the Son. That Spirit is, so to speak, organized within him by the Son. It is the manifestation of the new nature--of which more anon. The fact to note at present is that this is not an organic correspondence, but a spiritual correspondence. It comes not from generation, but from regeneration. The relation between the spiritual man and his Environment is, in theological language, a filial relation. With the new Spirit, the filial correspondence, he knows the Father and this is Life Eternal. This is not only the real relation, but the only possible relation: "Neither knoweth any man the Father save the Son, and he to whomsoever the Son will reveal Him." And this on purely natural grounds. It takes the Divine to know the Divine--but in no more mysterious sense than it takes the human to understand the human. The analogy, indeed, for the whole field here has been finely expressed already by Paul: "What man," he asks, "knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. Now we have received, not the spirit of the world, but the Spirit which is of God; that we might know the things that are freely given to us of God." [1] [1] 1 Cor. ii. 11, 12.
