Death' is the severing of this created oneness. God's design is seen in Genesis 1 as God sets out to order the cosmos which came into being by the power of His omnipotent Word. His work encompasses the days of the Creation Week and is punctuated by repeated acts of judgment whereby the creation is morally assessed as 'very good'. Every aspect of life functions symbiotically with the other created components to form a unified, living fabric. The concept of oneness should inform our understanding of created life.
Created life is a system of cohesive codependencies which complement and complete one another.
We see as well that the Creator is also the Judge of Creation. Life is not a morally neutral phenomena, but is inherently capable of being evaluated by the Creator. The couple are presented to us as the apex of God's creation work. With the man and the woman properly placed and functioning, we see a cosmos ordered to the glory of God. The entire picture is one of grace.
