How can humanity be held responsible for Adam's original sin? Study Romans 5 with context, apologetic analysis, and cross-references.
Dr. Lucas D. Shallua Commentary · ROMANS 5 — PEACE WITH GOD AND THE TWO ADAMS
Adam acted as the federal head and natural root of all humanity. His choice plunged his descendants into spiritual bankruptcy. Conversely, this same principle of representation allows Christ, the Second Adam, to represent believers, imputing His righteousness to us. The principle of representation is woven into the fabric of human existence. We are all represented by someone—either Adam or Christ.
No. Paul defines all within their respective covenant heads: all who are in Adam experience condemnation, while all who are in Christ—those who receive the abundance of grace—receive justification. The all in the second clause is coextensive with those who receive the gift. It is not a blanket universalism; it is a covenant particularism.
The trespass brought condemnation through one man's sin. The free gift brought justification through one man's obedience. The trespass was one act of disobedience; the free gift covers many trespasses. The free gift is greater in scope, greater in power, and greater in result. Grace is not the mirror image of sin; it is the overwhelming remedy.
Having established the doctrinal foundation of justification by faith in chapters 3 and 4, Paul transitions in chapter 5 to explain the grand results, security, and assurance of this new standing before God. The chapter moves from the benefits of justification to the cosmic scope of redemption, framing the work of Christ as the reversal of Adam's fall. This is one of the most theologically rich chapters in all of Scripture.
The universal reality of human mortality confirms the biblical worldview. Death is not a natural component of original human design but an intrusive penalty brought into the physical world through sin. The universality of death across all cultures and eras testifies to the universality of sin and the need for a Savior. If death is universal, then the remedy must be universal in its offer, even if particular in its application.
