Paul's Response to Sin Argument in Romans
Paul confronts a recurring objection to his gospel throughout Romans: if justification comes through grace apart from works, does this license continued sin? The question surfaces explicitly in Romans 6:1—"Shall we continue in sin, that grace may abound?" [2]—and reflects the controversy that dogged Paul's ministry. Charles Hodge notes that this objection "has been reiterated a thousand times since it was urged against the Apostles," precisely because the doctrine of justification by faith "seems so unreasonable" to those who assume moral performance must ground acceptance with God [5]. The very persistence of this charge confirms that Paul was teaching something genuinely radical about grace.
The Structure of Paul's Argument
Paul's response unfolds across Romans 6–8, moving from union with Christ to the Spirit's enabling power. In Romans 6, he grounds his answer in baptismal theology: believers have died with Christ and been raised to new life, making continued sin a contradiction of their identity [6]. John Gill observes that Paul "refutes the charge brought against it as a licentious doctrine" by demonstrating that justified persons are bound "by the strongest arguments, and with the best of motives to holiness of life and conversation" [6]. The logic is participatory, not merely legal: those united to Christ in his death cannot simultaneously remain enslaved to sin.
The objection itself reveals a misunderstanding of grace. Paul had just declared in Romans 5:20 that where sin increased, grace abounded all the more, prompting the question whether sin therefore "does not matter in the Christian life" [9]. But Paul's doctrine never separates justification from transformation. The same grace that justifies also sanctifies, destroying "the dominion of sin" even as remnants of sin persist to humble believers "under a consciousness of their own weakness" [7]. Calvin's formulation captures the tension: sin ceases to reign but does not cease to dwell in the regenerate.
Sin's Relationship to the Law
Romans 7 complicates the picture by exploring how the law itself becomes an occasion for sin. Paul writes, "Sin, finding occasion through the commandment, produced in me all kinds of coveting. For apart from the law, sin is dead" [1]. The law, though holy and good, exposes and even provokes the sinful nature: "Sin, finding occasion through the commandment, deceived me, and through it killed me" [4]. This is not a defect in the law but a revelation of sin's power. The law demonstrates human inability, showing that moral striving cannot overcome the flesh's weakness.
Interpreters have long debated whether Romans 7:14–25 describes pre-conversion struggle or the ongoing conflict in believers [8]. Matthew Henry notes that some apply it "to the struggles that are in a convinced soul, but yet unregenerate," while others see "the struggles that are in a renewed sanctified soul, but yet in a state of imperfection" [8]. The ambiguity may be deliberate: Paul's description captures both the futility of law-keeping apart from Christ and the reality that even believers experience the tension between willing good and doing evil.
The Resolution in Romans 8
Paul's answer culminates in Romans 8:3, where God accomplishes "what the law couldn't do, in that it was weak through the flesh" by sending his Son "in the likeness of sinful flesh and for sin" to condemn sin in the flesh [3]. The law's weakness was not intrinsic but circumstantial—it could diagnose sin but not defeat it. Christ's incarnation and atoning death break sin's power, enabling the Spirit to produce the righteousness the law required but could not generate.
The progression from Romans 6 through 8 thus answers the sin objection on multiple levels: union with Christ makes continued sin existentially contradictory (chapter 6), the law's role is diagnostic rather than salvific (chapter 7), and the Spirit enables what human effort cannot achieve (chapter 8). Paul's doctrine of grace does not minimize sin but takes it more seriously than moralism does, recognizing that only divine intervention can address the depth of human bondage. The charge of antinomianism misses how thoroughly Paul's gospel reorients the believer's identity and empowers transformation through the indwelling Spirit.
