Have a theological question?

Romans 3:21 – 26; 5: 12 – 21 There is a word that modern culture has largely abandoned, “sin.” We prefer softer substitutes: mistakes, poor choices, moral failures, character flaws. But the Apostle Paul refuses to let us settle for comfortable euphemisms.

At the heart of Paul’s letter to the Romans lies a tension that defines the human condition: the absolute righteousness of God and the pervasive sinfulness of humanity. These two realities are not merely theological abstractions; they shape the way we understand ourselves, our world, and our need for redemption.

In Romans 3 and 5, he delivers a diagnosis so thorough, so universal, that no one is left standing outside its reach. "For all have sinned and fall short of the glory of God" (Romans 3:23). Paul is not speaking of a troubled minority, a criminal class, or the especially corrupt.

He means every human being who has ever drawn breath. He has spent the first two and a half chapters of Romans building this case; the pagan world is without excuse; the moral philosopher who judges others is equally guilty, and even those who possess God's law have not kept it.

The whole world stands accountable before God (Romans 3:19). Two of the most beautiful words in all of Scripture appear in Romans 3:21 “but now.” After the long, unflinching diagnosis, after the verdict has been read and the silence has settled, Paul pivots: "But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it; the righteousness of God through faith in Jesus Christ for all who believe" (Romans 3:21–22). “The righteousness of God” here is not simply His moral perfection, though it includes that; it is His covenantal faithfulness, His unwavering commitment to act justly and to fulfill His promises.

Yet this raises a profound dilemma: how can a righteous God justify unrighteous people? How can He remain just while declaring sinners to be righteous? It is not merely that God demands righteousness from us, though He does. It is that God himself provides the righteousness He demands.

He does not stand at the finish line calling for us to run faster while our legs are broken. He comes down, takes our broken condition upon Himself, and carries us across. Paul explains how this is possible. God put forward Christ Jesus so that we are “justified freely by His grace through the redemption that is in Christ Jesus” (Rom 3:24).

Justification is a legal declaration; God pronouncing the guilty to be righteous. But it is not arbitrary, it is grounded in the redemptive work of Christ, who became a “propitiation by his blood, to be received by faith" (Romans 3:25). The word “propitiation” is an altar word, a temple word, a sacrificial language.

God is not merely offended by sin, He is rightly, justly, perfectly opposed to everything that corrupts and destroys what He has made and whom He loves. Sin required a reckoning, and in Christ, that reckoning came; not upon us, but upon Him. This is the heart of the gospel.

At the cross, Jesus bears the full weight of sin’s penalty. Sin is not ignored; it is judged. Christ, who knew no sin, became sin on our behalf. His blood was not the blood of another animal laid upon another altar. It was the blood of the eternal Son, and it was sufficient, perfectly, finally, completely sufficient, to absorb the just penalty for every sin of every person who would ever trust in Him.

God’s justice is not set aside; it is satisfied. His righteousness is not compromised; it is displayed. Paul makes this explicit: God did this “to demonstrate His righteousness… so that He might be just and the justifier of the one who has faith in Jesus” (Rom 3:25–26).

It speaks of the satisfaction of God's righteous wrath against sin. Here we encounter the paradox of the gospel: God’s justice and mercy meet in the person of Christ. The cross is not merely a demonstration of love; it is a vindication of God’s righteousness.

In Romans 5, Paul expands this vision by placing it within the broader narrative of humanity. He draws a sweeping contrast between two men, two kingdoms, two distinct realities. Adam is the first man, the head of humanity in its fallenness. Christ is the second man, the Last Adam, the head of a new redemptive humanity.

But notice how Paul stacks the comparison. "Sin came into the world through one man, and death through sin, and so death spread to all men because all sinned" (Romans 5:12). Adam's transgression was not merely personal. It was federal, he stood as the head and representative of the entire human race.

When he fell, we fell in him. The poison entered the bloodstream of humanity before any of us had the chance to choose otherwise. This is a hard truth! Paul is not writing a philosophical treatise to satisfy our sense of fairness. He is writing to explain the depth of the problem so that the depth of the solution might be fully appreciated.

This is why sin feels so pervasive, so inescapable. It is not merely something we do, it is a condition we inherit. We need to view sin as not merely the breaking of rules; it is the failure to reflect God’s glory, the distortion of our created purpose.

We were made to bear His image, to live in communion with Him, and to manifest His character in the world. Sin fractures that image, alienates us from God, and places us under His just judgment. Paul insists that what Christ accomplished is not merely equal to what Adam ruined, it is vastly greater. "The free gift is not like the trespass.... the free gift following many trespasses brought justification" (Romans 5:15-16). "Where sin increased, grace abounded all the more" (Romans 5:20).

The contrast is striking! This is not a close contest nor is it a narrow rescue. This is a flood of grace overwhelming a flood of ruin. Adam's sin brought condemnation; Christ's righteousness brings justification. Adam's transgression initiated the reign of death; Christ's obedience initiates the reign of life.

The one who is in Adam inherits guilt and mortality. The one who is in Christ inherits righteousness and eternal life. "For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous" (Romans 5:19).

This is the great exchange. For the believer, this truth reshapes our identity. We are no longer defined by our sin but by Christ’s righteousness. Our sin transferred to Him; His righteousness transferred to us. Not because we earned it, not because we deserved it, but because God, in His own sovereign freedom, determined that His glory would be displayed most brilliantly through mercy, a mercy that is entirely just, because the debt was entirely paid.

These passages are not merely theological architecture to admire from a distance. They are the ground beneath our feet, the air in our lungs. To understand God’s righteousness rightly is to be humbled. There is no room for boasting, for all stand equally in need of grace.

At the same time, it is to be deeply assured. Our standing before God does not rest on our fluctuating performance but on the finished work of Christ. When we sensed the weight of our sin today, that creeping awareness that we are not who we ought to be, Paul would say: you are not wrong about the diagnosis.

The problem is real. But the remedy is greater still. We are not called to minimise our sin or rehabilitate ourselves into someone worthy of God's favour. We are called to bring our full poverty before a God who is rich in mercy, and to receive through faith alone, in Christ alone, a righteousness that is not our own.

This assurance frees us from both despair and pride. We need not despair, for our sin, however great, has been dealt with at the cross. And we need not be proud, for our righteousness is not our own. It is a gift, received by faith. Moreover, this truth calls us to a life of gratitude and transformation.

While justification is a once-for-all declaration, it leads inevitably to sanctification, a life increasingly shaped by the righteousness we have received. We are called to reflect in our conduct what has been declared over us in Christ. In a world that often minimises sin or redefines righteousness according to human standards, Paul’s words call us back to reality.

Sin is real, pervasive, and deadly. But God’s righteousness is greater, His grace more abundant, and His provision in Christ sufficient. And so the question is not whether we will stand before God, but on what basis. Paul’s answer is clear: not on the basis of our works, our moral efforts, or our religious achievements, but on the basis of Christ alone.

Grace reigns. Not sin. Not death. Not shame. "Grace reigns through righteousness, leading to eternal life through Jesus Christ our Lord" (Romans 5:21). Receive it. Rest in it. Let it reshape everything. "Thanks be to God for his inexpressible gift!" (2 Corinthians 9:15)
