I think there is a tendency to speak of Death as the real enemy of God and life as its solution. We speak of death as the "great enemy." However, as Byron pointed out in a wonderful post some time ago, death is not the great enemy but the last enemy. The great enemy is sin, and we should not forget it.
In this, I found this quote from Oliver O'Donovan deeply helpful:
"The resurrection restores the life of all mankind, reversing the effects of sin; it reorders the disorder of which death is the emblem, and vindicates God's original act of creation." (Desire of the Nations, 142).At the end of the day, a gospel where death is the ultimate enemy will be close, but finally inadequate.
