Chapter 17, Paragraph I
The Certainty of Perseverance
Summary
This opening paragraph declares one of the most comforting truths in all of Scripture: that those whom God has accepted in His Beloved Son, called by His Spirit, and sanctified by His grace can never totally nor finally fall away from the state of salvation. Though they may stumble, they will not be cast off. Though they may wander, they will be restored. The same grace that called them will keep them to the end.
This perseverance is not the product of human resolve but the promise of divine faithfulness. Salvation begins with God’s sovereign choice and ends with His unbreakable commitment. The saints persevere because God preserves. He who justified them will sanctify them, and He who sanctified them will glorify them. Their faith may falter, but the hand of Christ never lets go. His grip is stronger than their weakness, His intercession more constant than their frailty.
Thus, the perseverance of the saints is not presumption, but promise—the settled confidence that God finishes what He begins. The believer’s security rests not in his steadfastness, but in the steadfast love of God. This is the great comfort of the gospel: that the saints are kept by the power of God through faith unto salvation, ready to be revealed in the last time.
Historical Context
The Westminster Divines here stood against both Arminianism and Roman Catholicism, which taught that true believers could finally fall from grace. Drawing from Augustine, Calvin, and the apostolic witness, they affirmed that election, calling, and sanctification are effectual and enduring. Grace once given cannot be lost, for it is grounded not in the instability of human will, but in the eternal decree and covenant of God.
The Puritans viewed this doctrine not as license for carelessness, but as fuel for endurance. It was meant to steady trembling hearts, strengthen weary saints, and inspire gratitude for the faithfulness of Christ. As Thomas Watson wrote, “God’s love to His elect is like the sun—He may hide His face, but He never withdraws His light.”

Summary Statement
Chapter 17, paragraph I teaches that the salvation of the elect is secure from beginning to end. God’s grace not only saves—it sustains. The saints are not held fast by their grip on God, but by God’s grip on them. His covenant love cannot fail, His promises cannot break, His purpose cannot be overturned.
Here lies the believer’s peace: though we change, He remains the same; though we stumble, He upholds; though we are weak, His grace is sufficient. Perseverance is not our achievement—it is God’s faithfulness written across our story, from election to eternity.
Chapter 17, Paragraph 2
The Grounds of Perseverance
Summary
This paragraph unfolds why the saints persevere. Their perseverance depends not upon their own free will or moral strength, but upon the unchanging love and purpose of God the Father, the finished work and continual intercession of Christ the Son, the indwelling of the Holy Spirit, and the inviolable nature of the covenant of grace.
First, it rests upon the immutability of election—God’s eternal decree cannot fail. What He has purposed in love He will perform in power. Second, it stands upon the efficacy of Christ’s mediation—His obedience and sacrifice once secured salvation, and His intercession now maintains it. Third, it depends upon the abiding presence of the Spirit, who dwells in believers as the seal and guarantee of their inheritance. Finally, it is assured by the covenant of grace, which promises that God will be their God and they His people forever.
These divine realities together ensure the certainty of perseverance. The believer’s security is therefore as unchangeable as God Himself. The saints’ assurance is not in their own consistency, but in the Father’s decree, the Son’s merit, the Spirit’s indwelling, and the covenant’s promise—all of which are infallible and everlasting.
Historical Context
In opposing the Remonstrant (Arminian) position that believers may fall away, the Westminster Divines emphasized that perseverance flows from the nature of grace itself. If election is eternal, if redemption is complete, if intercession is unceasing, and if the Spirit’s indwelling is irrevocable, then perseverance is inevitable.
This paragraph reflects the high Trinitarian harmony of Reformed soteriology: the Father elects, the Son redeems, and the Spirit preserves—all working inseparably to bring the saints to glory. To deny perseverance would be to suggest failure in the divine will, weakness in Christ’s atonement, or fragility in the covenant—all impossible for the God who cannot lie.

Summary Statement
Chapter 17, paragraph II declares that the perseverance of the saints is not a human achievement but a divine certainty. The triune God Himself ensures the believer’s final salvation. The Father’s electing love cannot change, the Son’s priestly work cannot fail, the Spirit’s indwelling cannot depart, and the covenant of grace cannot be broken.
The Christian’s assurance, therefore, is built on granite, not sand. It rests on eternal love, not fleeting willpower. The God who began salvation sustains it, and what He decreed in eternity He will accomplish in time. The believer’s perseverance is the echo of God’s immutability—unshaken, unfailing, and everlasting.
Chapter 17, Paragraph 3
The Reality of the Saints’ Falls and God’s Preserving Mercy
Summary
This final paragraph acknowledges that though believers cannot fall away from grace, they may, through temptation, weakness, or neglect, fall into grievous sin and remain there for a time. The confession is realistic about the Christian life: perseverance does not mean perfection. Saints may stumble deeply—David in adultery, Peter in denial—yet God’s grace will not let them go.
Such falls are costly. They incur God’s fatherly displeasure, grieve the Holy Spirit, diminish spiritual comfort, harden the heart, wound the conscience, harm the witness of the Church, and invite divine chastisement. Sin brings misery even to the redeemed. But God’s covenant mercy endures; He restores His people through repentance and discipline. Their faith may be shaken but not destroyed. Their relationship may be strained but not severed. Like a loving Father, God may withdraw the light of His countenance for a season, but never His covenant love.
Thus, perseverance does not promise a sinless path—it promises a faithful Shepherd. The believer may wander, but he will be sought and brought home. God’s preserving grace is stronger than the believer’s greatest failure, and His mercy more enduring than human frailty.
Historical Context
The Westminster Divines, shaped by Scripture and pastoral experience, wrote this paragraph to temper assurance with realism. They opposed both Perfectionism, which denied ongoing sin in the believer, and Despair, which feared that serious sin proved reprobation. Their theology reflected a deep understanding of sanctification as a warfare that continues until glory.
The Puritans often emphasized the restorative mercy of God: His covenant may bring chastisement, but never abandonment. Like the prodigal’s father, He disciplines to reclaim, not to reject. This paragraph served to comfort backsliding saints and to warn complacent ones—declaring that sin has consequences, but not the power to undo redemption.

- Luke 22:31–32 – “Satan demanded to sift you like wheat, but I have prayed for you that your faith may not fail.”

Summary Statement
Chapter 17, paragraph 3 brings the doctrine of perseverance down to the realities of Christian experience. The saints’ perseverance is certain, but their obedience is frail. They may fall, but not fall away. Their faith may flicker, but not fail. The covenant may darken with chastisement, but never dissolve.
Here shines the tenderness of divine grace: the same hand that disciplines also restores. The Shepherd who calls His sheep by name will not lose one of them. The believer may wander far, but the Father’s mercy reaches farther still. Though sin may cloud the light of His countenance, it cannot extinguish His love. The saints persevere not because they are strong, but because God is faithful—and His faithfulness endures forever.
