Man’s problem has always been one of faith-faith/trust in God-because only a God could guarantee that this universe holds any kind of future for us anyway. We cannot know or guarantee this for ourselves whether we exist in some edenic state or in this particular life. Because we are* creatures.*
To the extent that one has faith, which is what Christ’s advent is all about producing or restoring, death becomes a loss-but a temporary, not a final one. So a purpose of death, along with the other evils that threaten us throughout this life, is to actually help produce this faith as we come to fully recognize our dependency on “Something” outside of ourselves.
This is a good thing. Humans tend to reject this dependency, this faith, preferring ourselves to God. This obstacle to faith is also known as pride, a very ugly and destructive human trait, one that sets itself up against God, and even, unreasonably, seeks to deny and defy death as we often tend to pursue ego-driven goals in life that are futile and worthless in the end.
But since death is a great equalizer, considering that all, from the least to the greatest, must succumb to it in the end, it can be a teacher, granting the wisdom that says that no man is the end-all and be-all of his universe. Faith, and ultimately, love, triumph over all. That’s the message of Christ’s willingly dying, then resurrecting. Death is an enemy, but one that, together with grace, can help teach us humility and right perspective.
