I think you may be misconstruing the concept of death in this context. The death referred to as the "wages of sin" is eternal death. All of our earthly bodies must pass away, but the spiritual bodies of those of us who are saved will live forever. In 1 Corinthians, Paul wrote ...
"So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. If there is a natural body, there is also a spiritual body. So it is written: “The first man Adam became a living being; the last Adam, a life-giving spirit. The spiritual did not come first, but the natural, and after that the spiritual. The first man was of the dust of the earth; the second man is of heaven." (1 Corinthians 15:42-47)
The reason for the death of our earthly bodies becomes clear when you consider that this world has existed much longer than the life span of any human being. If there were no physical death, the earth would be pretty crowded with believers. God addressed this issue early in Genesis when He realized that having mankind live hundreds of years was impractical. "Then the Lord said, 'My Spirit will not contend with humans forever, for they are mortal; their days will be a hundred and twenty years.'” (Genesis 6:3)
Therefore, the death we experience is only temporary. Our spiritual bodies will live forever in the presence of the Lord.
