A Biblical Theology of Repentance
1. Repentance as a Response to the Gospel
The Bible consistently presents repentance as the necessary response to the Gospel of Jesus Christ. When Peter preached at Pentecost, the people asked, “Brothers, what shall we do?” His answer was clear: “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins” (Acts 2:37–38). Repentance, then, is not an optional extra but the posture of one who has heard the Gospel announcement that Jesus is Lord.
Repentance is more than an emotional reaction of regret or sorrow. It is an act of allegiance to Christ the King. To repent means to turn from the false lords of this world and to embrace the reign of Jesus, submitting to his rule and entering into the life of the kingdom.
2. The Nature of True Repentance
Biblical theology distinguishes true repentance from false forms of sorrow or ritual. True repentance includes several interconnected realities:
Allegiance to Christ – Repentance acknowledges Jesus’ kingship (Matt. 4:17; Acts 17:30–31).
Turning from Sin – While not merely regret, repentance necessarily involves abandoning former sinful practices (Ezek. 18:30).
Faith and Repentance Together – Repentance and faith are two sides of the same coin; to trust in Christ is to turn away from self-rule and sin (Mark 1:15).
Ongoing Practice – Repentance is not only the initial response to the Gospel but also a continual aspect of Christian life (1 John 1:9).
Repentance is never self-sanctification. The Gospel proclaims that Jesus has already borne sin on the cross and sanctified his people by his blood (Heb. 10:10). Repentance, therefore, is enacted participation in the holiness already secured in Christ.
3. Repentance and Regeneration by the Spirit
The Bible teaches that repentance and regeneration belong together. The Holy Spirit awakens the heart to see the reality of sin and the lordship of Christ. Repentance is evidence that regeneration has taken place, and yet intentional repentance must also be enacted to demonstrate ongoing allegiance.
Regeneration: The Spirit gives new birth, opening eyes to the Gospel (John 3:5–8).
Repentance: The believer turns toward Christ in obedience and faith (Acts 20:21).
Baptism: Repentance and faith are publicly enacted in baptism, the sign of new covenant allegiance (Rom. 6:3–4).
This biblical pattern underscores that salvation is God’s work from beginning to end, but the human response of repentance is the God-ordained way to enter the new life of the kingdom.
4. The Struggle of Flesh and Spirit
Repentance is necessary because believers continue to live in the tension between flesh and Spirit (Gal. 5:16–17). Though Christ has already won the decisive victory over sin and death, Christians must daily turn away from old habits and live in the Spirit’s power.
This ongoing repentance does not re-earn salvation but demonstrates living allegiance to Christ. Repentance is not merely the doorway into the Christian life but the posture of discipleship until the last day when Christ consummates his kingdom.
5. Repentance and the Kingdom of God
When Jesus began his ministry, his first words were: “Repent, for the kingdom of heaven is at hand” (Matt. 4:17). Repentance is inseparable from the Gospel of the kingdom. To repent is to recognize the rule of Christ and to realign life under his authority.
This means repentance is not just about individual moral improvement but about covenantal participation in God’s people. To repent is to leave behind allegiance to idols, powers, and worldly kingdoms, and to embrace life in the church—the community where Christ reigns as Lord.
6. Distortions of Repentance in Popular Theology
In many places, especially in what Delgado has called the “Gospel of Middle America,” repentance has been reduced to mere intellectual assent or a private decision. This truncated view emphasizes belief without allegiance, forgiveness without discipleship, and faith without church participation.
The Bible offers a richer theology of repentance:
Not mere belief – Even demons believe (James 2:19).
Not mere regret – Judas regretted his betrayal but did not repent (Matt. 27:3–5).
Not self-improvement – Repentance is empowered by the Spirit, not human resolve (Rom. 8:13).
Biblical repentance is an enacted, embodied response to the Gospel that results in transformed lives and communities.
7. Repentance and the Last Days
The New Testament ties repentance directly to eschatology. Peter warns that God is “patient toward you, not wishing that any should perish, but that all should reach repentance” (2 Pet. 3:9). Repentance delays judgment, but the day of the Lord will come (2 Pet. 3:10).
Thus, repentance carries both urgency and hope:
Urgency: Repent now, for judgment is certain (Acts 17:30–31).
Hope: Repentance leads to life, as God grants forgiveness and refreshment (Acts 3:19–21).
In the last days, the church calls all nations to repent and bow before Christ the King, anticipating the final renewal of all creation.
8. Repentance as a Lifelong Calling
Biblical theology presents repentance not as a one-time act but as a lifelong calling. The church is a community of repentance, continually confessing sin, turning back to Christ, and proclaiming his kingdom until he comes.
Practically, this means:
Daily confession of sin (1 John 1:9).
Pursuing reconciliation with others (Matt. 5:23–24).
Walking in new obedience (Rom. 6:12–13).
Bearing fruit consistent with repentance (Matt. 3:8).
Repentance is the rhythm of Christian life, sustained by the Spirit, rooted in the cross, and pointing forward to the consummation of the kingdom.
