We should face the death of our bodies with peace, joy and gratitude to God, who gave it to us as a temporary gift.
Might I point out this is true for both views here, it is not somehow changed because we are under a curse and moving on to a better life. Knowing we are redeemed and passing on to a better place gives us much more joy and gratitude than if we just fed some worms and became mulch.
Paul's reference to Adam and Christ as persons who introduced death and life (correspondingly) should also be understood spiritually, as salvation is about passing from spiritual death to the life of the spirit, and not about the eternal preservation of our bones or kidneys.
Well, amen. This is true in both views. Physical death was never the "only" death in Scripture, that's never been the case. It's the "lesser" death, the merely "symbolic" death of something so much worse and more terrible, our spiritual death because of sin.
Biological death, just as metabolism or reproduction, is inherent to biological life. It does not imply destruction of matter or energy, but rearrangement, reuse, within the big picture of life in the planet.
Yes, indeed, from a naturalistic perspective where humankind is nothing more than some meat on a bag of bones, from dust we return, and to dust we shall go. But we know we are made in the image of God, and we know that when our body decomposes something has gone, something is missing, our real self is no longer there, the body was just a temporary housing, a tent in a strange land.
Now we need to see that even though the human body's decomposition can help some worms and grass, this is not to prove or imply that this an ideal picture. We all desire institutionally to experience life, to enjoy life, to really find some experience of happiness, and that dying, if that were all there was to it, is a bad thing because it ends all our hopes for anything better. And we recognize that if we put a precious work of art in the ground, it may decompose and help out some worms and grass, but that precious work of art was meant for better things, and expresses something far higher in worth and dignity than becoming worm food. We recognize that marring a work of art, watching it fade away, is an inherently negative and improper thing, because we see that death is an expression of loss and a destructive perversion of the idea.
Death, indeed, is the wages of sin, both physical death, and spiritual death—that far greater judgment for all our sins in God's eternal wrath.
