The confession that death is a payment for sin, although it is not proved by science, is not disproved by it, either. It simply lies outside the pale of scientific investigation and beyond its reach. Moreover, this confession does not need the evidence of science. It is based on the divine testimony and is confirmed, hour by hour, in the fear of death by which men, throughout their lives, are subject to bondage (Hebrews 2:15). Whatever, therefore, may be said in evidence of its necessity or in defense of its legitimacy, death remains unnatural. It is unnatural with a view to the essence and destiny of man in his connection with his creation after the image of God, for fellowship with God is incompatible with death. God is not God of the dead, but of the living (Matthew 22:32).
On the contrary, death is altogether natural for fallen man, for sin, when it is finished, brings forth death (James 1:15). After all, in Holy Scripture, death is not to be equated with annihilation, any more than life includes nothing more than naked existence. Life is enjoyment, blessedness, superabundance, and death is misery, poverty, hunger, the want of peace and blessedness. Death is dissolution, separation of what belongs together. Man, created in God’s image, is at home in communion with God. There, he lives, fully, eternally, blessedly. But, when he severs that fellowship, he dies in that same moment and continues, always, to die further. His life is deprived of joy, peace, and blessedness, and has become a dying in sin. And this spiritual death, this separation between God and man, continues in the body and culminates in eternal death. For, at the separation of body and soul, man’s lot is determined, but his existence is not over. For it is appointed unto men once to die and, after that, the judgment (Hebrews 9:27). And who can stand in that judgment?
