But even if we grant that physical death is seen uniformly in scripture as a result of sin, is it only physical death that’s in view? Is death an evil, “the last enemy,” for biblical writers simply because it means that earthly life stops? Or is it because it threatens separation from God? (Cf. Psalm 6:5) Of course a biblical view of human death is multifaceted and there is considerable development from the earliest strata of the Old Testament through the New. But we can’t really separate the reality of physical death from its psychological and spiritual affects. In what I once called rather mouth-fillingly “hermeneutical retrocausality,” sin gives new meaning to dying that was a reality even before humanity came on the scene.
