The words of Scripture which preface this inquiry contain an explicit and original statement of the Law of Biogenesis for the Spiritual Life. "He that hath the Son hath Life, and he that hath not the Son of God hath not Life." Life, that is to say, depends upon contact with Life. It cannot spring up of itself. It cannot develop out of anything that is not Life. There is no Spontaneous Generation in religion any more than in Nature. Christ is the source of Life in the Spiritual World; and he that hath the Son hath Life, and he that hath not the Son, whatever else he may have, hath not Life. Here, in short, is the categorical denial of Abiogenesis and the establishment in this high field of the classical formula _Omne vivum ex vivo_--no Life without antecedent Life. In this mystical theory of the Origin of Life the whole of the New Testament writers are agreed. And, as we have already seen, Christ Himself founds Christianity upon Biogenesis stated in its most literal form. "Except a man be born of water and of the Spirit he cannot enter into the Kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is Spirit. Marvel not that I said unto you, ye must be born again."[37] Why did He add _Marvel not_? Did He seek to allay the fear in the bewildered ruler's mind that there was more in this novel doctrine than a simple analogy from the first to the second birth? The attitude of the natural man, again, with reference to the Spiritual, is a subject on which the New Testament is equally pronounced. Not only in his relation to the spiritual man, but to the whole Spiritual World, the natural man is regarded as _dead_. He is as a crystal to an organism. The natural world is to the Spiritual as the inorganic to the organic. "To be carnally minded is _Death_."[38] "Thou hast a name to live, but art _Dead_."[39] "She that liveth in pleasure is _Dead_ while she liveth."[40] "To you he Hath given Life which were _Dead_ in trespasses and sins."[41] It is clear that a remarkable harmony exists here between the Organic World as arranged by Science and the Spiritual World as arranged by Scripture. We find one great Law guarding the thresholds of both worlds, securing that entrance from a lower sphere shall only take place by a direct regenerating act, and that emanating from the world next in order above. There are not two laws of Biogenesis, one for the natural, the other for the Spiritual; one law is for both. Wherever there is Life, Life of any kind, this same law holds. The analogy, therefore, is only among the phenomena; between laws there is no analogy--there is Continuity. In either case, the first step in peopling these worlds with the appropriate living forms is virtually miracle. Nor in one case is there less of mystery in the act than in the other. The second birth is scarcely less perplexing to the theologian than the first to the embryologist.
