Overview

Faith’s companion grace. Repentance unto life is an evangelical grace by which the sinner, grieved by sin and apprehending God’s mercy in Christ, turns from sin to God with full purpose of new obedience. The Confession insists repentance does not earn pardon (that is Christ’s work alone), yet no one may expect pardon without it; and it is to be ongoing, particular, and met with God’s certain mercy.

The Confession, Section by Section

15.1–15.2 — The nature of repentance

Repentance unto life is an evangelical grace, the doctrine whereof is to be preached by every minister of the gospel, as well as that of faith in Christ.

By it, a sinner, out of the sight and sense not only of the danger, but also of the filthiness and odiousness of his sins, as contrary to the holy nature, and righteous law of God; and upon the apprehension of his mercy in Christ to such as are penitent, so grieves for, and hates his sins, as to turn from them all unto God, purposing and endeavouring to walk with him in all the ways of his commandments.

Scripture Proofs (ESV):

“Repent therefore, and turn back, that your sins may be blotted out.” (Acts 3:19, ESV)

“…godly grief produces a repentance that leads to salvation without regret.” (2 Cor. 7:10, ESV)

Further proofs: Ezek. 18:30–31; 36:31; Joel 2:12–13; Ps. 51:4; Luke 1:16–17; Acts 11:18.

Exposition: Repentance is “evangelical” — it flows from the gospel, not toward it as a payment. It has two motions: a turning from sin (grief and hatred of sin “as contrary to the holy nature… of God”) and a turning to God (purposing “new obedience”). Crucially, it arises “upon the apprehension of his mercy in Christ” — we repent because we have glimpsed grace, not in order to deserve it. It is “godly grief,” distinct from mere worldly remorse over consequences.

15.3 — Repentance does not merit pardon, yet is necessary

Although repentance be not to be rested in, as any satisfaction for sin, or any cause of the pardon thereof, which is the act of God’s free grace in Christ; yet is it of such necessity to all sinners, that none may expect pardon without it.

Scripture Proofs (ESV):

“…unless you repent, you will all likewise perish.” (Luke 13:3, 5, ESV)

Further proofs: Ezek. 36:31–32; Job 42:5–6; 2 Tim. 2:25; Acts 17:30–31.

Exposition: A careful balance, exactly parallel to faith. Repentance is not the ground or cause of pardon — that is “the act of God’s free grace in Christ” alone. Yet it is necessary: “none may expect pardon without it.” Pardon is by grace through faith; but the faith that receives Christ is always accompanied by repentance that turns from sin. You are not forgiven because you repent, but no impenitent person is forgiven.

15.4–15.5 — No sin too great; every sin to be repented of particularly

As there is no sin so small, but it deserves damnation; so there is no sin so great, that it can bring damnation upon those who truly repent.

Men ought not to content themselves with a general repentance, but it is every man’s duty to endeavour to repent of his particular sins particularly.

Scripture Proofs (ESV):

“If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” (1 John 1:9, ESV)

Further proofs: Rom. 6:23; Isa. 1:16–18; 55:7; Ps. 19:13; 51 (throughout); Luke 19:8.

Exposition: Two pastoral truths. First, no sin is too great for grace: the “true penitent” need never fear that any sin places him beyond Christ’s mercy. Second, repentance should be particular, not vague — naming and turning from specific sins, as David does in Psalm 51, not hiding behind a general “forgive all my sins.” (The Confession’s later sections also direct the penitent to confess to God always, and to those wronged where the sin is against them, while pointedly rejecting the necessity of private confession to a priest for pardon.)

Doctrinal Summary

Repentance unto life is an evangelical grace, to be preached alongside faith, by which the sinner — seeing both the danger and the odiousness of his sin, and apprehending God’s mercy in Christ — grieves for and hates his sin, turns from it all to God, and purposes new obedience. It does not satisfy for sin or cause pardon, which is God’s free grace in Christ, yet none may expect pardon without it. No sin is too small to deserve damnation, none too great to be pardoned in the true penitent; and believers are to repent of particular sins particularly.

Connections

• WLC Q76 — “Repentance unto life is a saving grace, wrought in the heart of a sinner by the Spirit and word of God, whereby… he so grieves for and hates his sins, as that he turns from them all to God, purposing and endeavouring constantly to walk with him in all the ways of new obedience.”
• WSC Q87 — “Repentance unto life is a saving grace, whereby a sinner, out of a true sense of his sin, and apprehension of the mercy of God in Christ, doth, with grief and hatred of his sin, turn from it unto God, with full purpose of, and endeavour after, new obedience.”
• WCF 14 (saving faith — repentance’s inseparable companion), WCF 11.5 (the justified renewing repentance under fatherly displeasure), WCF 13 (sanctification — the new obedience repentance purposes).
• Loci: Repentance (metanoia); conversion as the two sides of faith and repentance.

Pastoral & Practical Significance

This chapter guards two cliffs. Against the sinner who presumes — thinking grace means sin can be coddled — it says repentance is necessary; no impenitent soul should expect pardon. Against the sinner who despairs — convinced some sin has put him beyond hope — it says no sin is too great for the true penitent; God is faithful to forgive. The repentance the Confession describes is not groveling to earn God’s favor but the glad about-face of one who has glimpsed mercy in Christ. So repentance is not a one-time entry fee but a lifelong posture (cf. 11.5): the Christian keeps turning, particularly and specifically, from each sin to the Father whose mercy in Christ is sure. Worldly grief obsesses over consequences and self; godly grief turns to God and finds cleansing.

For Reflection

• Is my sorrow over sin “godly grief” that turns to God, or “worldly grief” that only fears consequences?
• Do I repent of particular sins particularly, or hide behind a vague “forgive all my sins”?
• Where am I tempted to presume on grace — or to despair of it? How does this chapter answer both?
