But the Biblical writers deal with man in the integrity of his being, and in his relations to God; they transcend the distinction of natural and moral, because for God it is not final: they are sensible of the unity in things which the everyday mind, for practical purposes, finds it convenient to keep apart. It is one great instance of this that they are sensible of the unity of sin and death. We may call sin a spiritual thing, but the man who has never felt the shadow of death fall upon it does not know what that spiritual thing is: and we may call death a natural thing, but the man who has not felt its natural pathos deepen into tragedy as he faced it with the sense of sin upon him does not know what that natural thing is. We are here, in short, at the vanishing point of this distinction--God is present, and nature and spirit interpenetrate in His presence. We hear much in other connections of the sacramental principle, and its importance for the religious interpretation of nature. It is a sombre illustration of this principle if we say that death is a kind of sacrament of sin. It is in death, ultimately, that the whole meaning of sin comes home to the sinner; he has not sounded it to its depths till he has discovered that this comes into it at last. And we must not suppose that when Paul read the third chapter of Genesis he read it as a mythological explanation of the origin of physical death, and accepted it as such on the authority of inspiration. With all his reverence for the Old Testament, Paul accepted nothing from it that did not speak to his conscience, and waken echoes there; and what so spoke to him from the third chapter of Genesis was not a mythical story of how death invaded Paradise, but the profound experience of the human race expressed in the story, an experience in which sin and death inter-penetrate, interpret, and in a sense constitute each other. To us they are what they are only in relation to each other, and when we deny the relation we see the reality of neither. This is the truth, as I apprehend it, of all we are taught either in the Old Testament or in the New about the relation of sin and death. It is part of the greater truth that what we call the physical and spiritual worlds are ultimately one, being constituted with a view to each other; and most of the objections which are raised against it are special cases of the objections which are raised against the recognition of this ultimate unity. So far as they are such, it is not necessary to discuss them further; and so far as the ultimate unity of the natural and the spiritual is a truth rather to be experienced than demonstrated, it is not probable that much can be done by argument to gain acceptance for the idea that sin and death have essential relations to each other. But there are particular objections to this idea to which it may be worth while to refer.
