". . . so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord." Romans 5:21
In Romans 5:12-21, Paul "is not saying merely that we have life for a time, after which life ends in death; nor is he aiming to explain the fact of such death. . . . What he is saying is rather that all that we call life . . . lies under the dominion of death. . . . Death rules supreme in this world. . . ." But since the resurrection of Christ "the new aeon has become actual fact in our world. Christ stands at the frontier between the two ages, outdating the old and blazing the way for the new. . . . In the new aeon, which burst upon man with the resurrection of Christ, life has come to dominion still more mightily."
Anders Nygren, Commentary on Romans, pages 22-23.
This life we live is not life. This life is a living death. This whole world is ruins brilliantly disguised as elegance. Christ alone is life. Christ has come, bringing his life into the wreckage called us. He has opened up, even in these ruins, the frontier of a new world where grace reigns. He is not on a mission to help us improve our lives here. He is on a mission to create a new universe, where grace reigns in life. He is that massive, that majestic, that decisive, that critical and towering and triumphant.
We don't "apply this to our lives." It's too big for that. But we worship him. And we boast in the hope of living forever with him in his new death-free world of grace.
