Only through and in the human person will the whole world come into a relationship with God.
The fall of humanity alienated the whole creation from God. It destroyed the cosmic harmony. Through the Fall, humanity became subject to the course of nature. This ought not to have happened. In the life of animals death is an expression of the power of procreation rather than of frailty. Through the fall of humanity, death also receives in nature an evil and tragic meaning. To the animal’s death means only the end of individual existence. Among humans death strikes at the personality; and personality is something more than mere individuality. The body is dissolved and subject to death because of sin. But the whole human person dies. The human person is composed of body and soul; therefore, the separation of body and soul means that the human person ceases to exist as a human person. The image of God fades. Death reveals that the human person, this creature made by God, is not only a body…The fear of death is only averted through the hope of resurrection and eternal life.
Death does not only mean that sin is revealed; it is also an anticipation of resurrection. God does not only punish fallen human nature by death, but also purifies and heals it.
The death on the Cross was not efficacious because it was the death of an innocent man, but because it was the death of the incarnated Lord. It was not a human being who died on the cross but God. But God died in His own humanity. He was Himself the resurrection and the life. (Georges Florovsky, On the Tree of the Cross, pp. 145-146, 148-149)
