Union with Christ, part 1 of 2
Sin, Salvation, and the Necessity of Resurrection: Rethinking the Problem the Gospel Solves
This essay marks a transition from the narrative framework developed in The Great Ascent video series found on my Tent to Temple YouTube channel into a more explicitly theological analysis. The goal here is not to abandon that narrative, but to examine it through categories familiar to Christian theology; particularly the doctrine traditionally called union with Christ. From that vantage point, the implications for justification and atonement begin to come into focus. What follows remains intentionally accessible, engaging the way sin and salvation are most often understood at the popular level within Protestant and evangelical contexts, rather than offering a full technical comparison with historical theological systems.
At a popular level, Protestant soteriology is often framed around a straightforward sequence: Adam disobeys, guilt enters the world, human nature is stained, and Christ’s death functions as a sacrificial remedy that cleanses this stain. Through faith, individuals are forgiven, declared righteous, and restored, at least in a legal sense, to innocence before God. This framework contains important and necessary truths. Adam’s disobedience matters. Sin does bring guilt. The cross does deal decisively with sin in a judicial and sacrificial sense. None of that is being rejected.
However, when this account functions as the entire explanation of the human problem, it leaves significant biblical data underexplained. In particular, it struggles to account for the pervasive role Scripture assigns to death; and especially for the centrality of resurrection in the New Testament.
The Genesis narrative presents death as the consequence of eating from the tree of the knowledge of good and evil: “In the day that you eat of it, you shall surely die.” If death is understood merely as an externally imposed penalty for rule-breaking, then the broader arc of Scripture becomes difficult to integrate. Most notably, resurrection begins to look like an optional add-on rather than a theological necessity. If guilt is the fundamental problem and forgiveness the full solution, then once sin is dealt with at the cross, resurrection seems unnecessary—perhaps a final reward for those already reconciled.
Paul explicitly rejects this logic. For him, resurrection is not supplemental. It is essential. He insists that if Christ has not been raised, believers are still in their sins. That claim only makes sense if the problem sin creates cannot be resolved by forgiveness alone. The cross, though central, does not exhaust the solution.
This points to a deeper diagnosis of sin itself. In Scripture, sin is not only a matter of guilt but also of corruption- corruption not merely in a moral or legal sense, but in an ontological one. When Adam eats from the tree, the issue is not simply disobedience. Humanity takes on a form of moral knowledge it is not yet constituted to bear. A mismatch is introduced between human nature and the weight of divine moral awareness. The result of that mismatch is not merely culpability but decay: mortality, corruption, death.
From this perspective, death is not best understood as a punishment imposed from without, but as the natural consequence of corruption from within. Scripture regularly speaks of death as a reigning power, an enemy, and a force that enslaves, not merely as a verdict handed down. Creation itself groans under its weight. Human bodies decay. Death must be defeated, not simply forgiven.
This reframing also reshapes how divine judgment and curse language function in the biblical narrative. God’s response to sin are not merely retributive; they are also preservative. They limit the spread of corruption and prevent its totalizing effects. Divine wrath, particularly in Paul, is best understood as God’s opposition to corruption because corruption destroys life. It is not arbitrary anger, but resistance to what unravels creation.
This is why reducing death to “spiritual separation” proves insufficient. Scripture consistently treats death as embodied, historical, and cosmic. Humans actually die. Bodies return to dust. Resurrection, therefore, cannot be optional. It addresses a problem forgiveness alone cannot reach.
If salvation were simply about returning humanity to a pre-fall state (restoring innocence or resetting the clock to Eden) then resurrection would be unnecessary. Cleansing and forgiveness would suffice. But the New Testament never frames salvation as a return to Eden. It frames it as an advance into glory. Humanity is not restored to ignorance but transformed into maturity. Knowledge is not removed but fulfilled. Paul’s contrast is not between knowing and not knowing, but between partial knowledge and completed knowledge.
The fundamental problem was never knowledge itself; it was knowledge without transformation. Forgiveness can remove guilt, but it cannot by itself produce righteousness. A cleansed heart still requires a new mode of life. A forgiven body still dies unless it is transformed.
Resurrection is God’s answer to corruption. It resolves the mismatch introduced in Adam- not by stripping humanity of moral awareness, but by giving humanity a form of life capable of bearing it. An incorruptible body. A spiritual body. A humanity finally aligned with divine life.
For that reason, it is more precise to say that human nature is not simply “totally depraved” as a result of Adam’s sin, but fundamentally corrupted by its effects. That distinction matters. It shifts the focus from sin as merely guilt-inducing to sin as life-destroying. And it clarifies why the gospel is not only about forgiveness, but about transformation.
The cross addresses sin.
The resurrection addresses death.
Together, they accomplish what neither could achieve alone.
This, I would argue, more closely reflects the story Scripture itself tells: the story in which resurrection is not the appendix of Christian theology, but its center of gravity.
