The Believer’s Transition from Enmity under the Pedagogical Law to Adoption and Definitive Sanctification: A Reformed Theological Exposition

I. The Second Use of the Law and the Pre-Regenerate State of Enmity

The believer’s journey from the state of enmity and rebellion, rooted deeply in the fallen human condition, toward the blessedness of divine adoption and ultimate sanctification is a profound testament to the unmerited sovereign grace of God. Classical Reformed theology emphasizes that the second use of the law—often described as the usus elenchticus or pedagogical use—functions not as a neutral moral guide but as a divine mirror exposing the depths of human depravity, restraining the outward manifestations of civic evil, and, most critically, driving the sinner to Christ as the only remedy for their fallen state (Galatians 3:24; Romans 3:20; cf. Calvin, Institutes 2.7.6–9). 

Far from being a mere set of moral instructions, this law confronts the pre-regenerate soul—whose very ousia or essence is bent toward rebellion and independence from God (Ephesians 2:1–3; Romans 8:7)—placing it under the weight of divine justice and revealing it as perpetually guilty before the holy bar of God. This alienation manifests not merely as episodic acts of transgression but as a comprehensive participation in the rebellion of “the father of lies” (John 8:44), where the unrenewed mind dwells in a phantasmagoric realm of self-deification, autonomous self-worship, and spiritual self-sufficiency, inevitably leading to spiritual death (Ephesians 2:12–16; Romans 6:23).

II. The Heresy of Universal Fatherhood and the Necessity of Regeneration

The false notion of a universal fatherhood of God—an idea that suggests all humanity is embraced equally within God’s divine family regardless of regeneration—stands as a categorical theological error. It conflates the general relation of Creator to creation with the specific, covenantal bond of adoption secured exclusively through union with the eternal Son. This error, often associated with liberal theological trajectories critiqued by figures like J.I. Packer and others, diminishes the radicality of election, effectual calling, and the necessity of the new birth. 

 Regeneration therefore occurs solely through the divine act of implanting the living and incorruptible seed of the Word (1 Peter 1:23; James 1:18), effectually translating the sinner from the domain of darkness into the glorious family of God (Colossians 1:13; Ephesians 1:5). This divine adoption is not merely a forensic or legal declaration but precipitates a radical ontological transformation.

III. Adoption, New Creation, and the Shepherd’s Internal Guidance

As articulated in the Westminster Larger Catechism (Q. 74), adoption involves a profound re-creation of the believer’s being: the old man is crucified with Christ, and the believer is reborn into a new reality—what Paul describes as a kainē ktisis, a new creation (2 Corinthians 5:17). This new creation is characterized by the infusion of a new heart, a new name, and an incorruptible nature no longer subject to the curse of sin (Ezekiel 36:26; Revelation 2:17; 1 John 3:1–2). 

Christ, the Good Shepherd (John 10:11, 27–28), now governs these regenerate sheep not through external constraints but through the internal and efficacious Word that sustains and guides the cosmos itself (Hebrews 1:3; Psalm 23). Their desires are reoriented by the inexhaustible springs of living water that flow from the eternal decrees of divine sovereignty (John 4:14; 7:38), rendering perseverance an inevitable fruit of the implanted Holy Spirit.

IV. Definitive and Progressive Sanctification: The “Already” and the “Not Yet”

This doctrinal framework reaches its apex in the distinction between definitive (or positional) sanctification and progressive sanctification. As John Murray compellingly argued, regeneration involves a decisive, once-for-all act that breaks the power of sin’s dominion over the believer, establishing a new status rooted in union with Christ, the Sanctified One (1 Corinthians 1:30; 6:11; Hebrews 10:10, 14). 

This initial act is a completed, definitive event—an unchangeable standing before God—while progressive sanctification is an ongoing, Spirit-empowered process whereby the believer is gradually conformed into the likeness of Christ. Though the residual effects of indwelling sin—the classical “flesh”—continue to exert influence (Romans 7:14–25; Galatians 5:16–17), the believer is empowered by the Spirit to reckon themselves dead to sin and alive to God (Romans 6:11). Weakness and struggle become the very theater where divine power is displayed (2 Corinthians 12:9).

V. The Reoriented Relationship to the Law and Eschatological Hope

This understanding decisively reorients the believer’s relationship to the law. No longer viewed as a covenant of works demanding self-justification, the law is understood as an expression of the Father’s will—placed within the believer through the indwelling Spirit—and fulfilled in Christ’s perfect obedience, who redeemed believers from its curse (Galatians 3:13; Romans 8:1–4). Even amid the ongoing fight against indwelling sin, the believer possesses full and unshakeable acceptance as a co-heir with Christ, perfected forever in the Beloved (Hebrews 10:14), with the ultimate hope that every tear will be wiped away in the eschaton (Revelation 21:4).

VI. Pastoral and Societal Implications: Illumination from Psalm 73

The pastoral and societal implications of this theological stance become especially vivid when examined through the lens of Psalm 73. Asaph’s crisis of faith—his near apostasy—arises from the empirical observation of the prosperity of the wicked, who indulge in deception, fraud, and the glorification of amoral power, all the while seemingly escaping divine justice (Psalm 73:3–12). Calvin’s exegesis underscores the temptation to impugn divine providence in such circumstances, especially when societal structures appear to favor corruption and injustice. 

Yet, Asaph’s entry into the sanctuary (miqdash) brings about a renewal of the mind: the apparent stability of the wicked is revealed as fleeting and illusory, destined for sudden destruction (Psalm 73:17–18), while the believer’s true portion is found in communion with God, guided by divine counsel, and secured by eschatological promises of glory (Psalm 73:23–26). Charles Spurgeon, in his Treasury of David, emphasizes this shift from empirical, carnal understanding to eternal perspective: the sufferings of the present moment are akin to evening sacrifices, their tears treasured as offerings upon the divine altar, ultimately transformed into eternal recompense. 

VII. Sovereign Design amid Moral Decline and the Triumph of Grace

In periods marked by moral decline—where evil advances from hidden schemes to entrenched societal strongholds—God sovereignly ordains affliction and hardship to detach His people from the false ladders of worldly self-validation, redirecting their gaze to the unapproachable light of divine glory (1 Timothy 6:16). Even as common grace recedes and the flesh communicates its deathly logic, the implanted Word, coupled with the springs of divine life within, secures the believer’s safety in the fold of Christ. The believer inhabits the dialectical tension of the “already” and the “not yet,” resting in the certainty of definitive sanctification while earnestly pursuing Christlikeness through progressive conformity. In this process divine sovereignty is magnified: the evils and corruptions within a fallen order are transformed into tools of divine sanctification, whereby the Father, through His wise and sovereign purposes, conforms His adopted children into the image of His eternal Son (Romans 8:28–29). To the Triune God alone belongs all dominion, glory, and praise—worthy of eternal adoration—whose sovereignty and grace extend from everlasting to everlasting, securing the final victory of His purposes for His redeemed. Amen.
