What does "grow in the grace and knowledge" mean in 2 Peter 3:18? Canonical Context Second Peter circulates as the apostle’s farewell letter, written “to those who have obtained a faith as precious as ours” (2 Peter 1:1). From start to finish the epistle confronts scoffers (3:3) and counterfeit teachers (2:1) while encouraging believers to live holy, expectant lives “looking for and hastening the coming of the day of God” (3:12). The closing line—“But grow in the grace and knowledge of our Lord and Savior Jesus Christ” (3:18)—functions as the climactic antidote to every danger listed before it. Literary Setting within the Epistle The command sits in a cascading series of imperatives (3:14 – 17): • “Make every effort to be found at peace, without spot or blemish.” • “Regard the patience of our Lord as salvation.” • “Be on your guard so you are not carried away by the error of the lawless.” The final “But grow …” replaces passivity with purposeful development. It also bookmarks the letter when paired with the opening prayer, “Grace and peace be multiplied to you through the knowledge of God and of Jesus our Lord” (1:2). Multiplication prayed for (ch. 1) becomes growth commanded (ch. 3). Original Language Analysis • “Grow” (auxanete, present active imperative, 2 person plural) depicts an ongoing, habitual expansion—never a once-for-all achievement. • “Grace” (charis) carries the dual sense of God’s unmerited favor and His empowering presence (cf. 1 Corinthians 15:10). • “Knowledge” (gnosis) in Petrine usage refers to relational, experiential knowledge of Christ, not mere data (1:3, 8). Thus the charge is: Keep increasing, together, in both the unearned favor God supplies and the experiential relationship that shapes understanding and conduct. Theological Significance of “Grace” Grace originates in God’s eternal character (Exodus 34:6) and is mediated through Christ’s atoning work (Romans 3:24). Believers “stand” in this grace (Romans 5:2) and are “strong” by it (2 Timothy 2:1). Growing in grace means: 1. Deeper awareness of dependence on Christ’s finished work (Galatians 2:20-21). 2. Greater empowerment for obedience (Titus 2:11-12). 3. Expanding generosity toward others (2 Corinthians 9:8). Theological Significance of “Knowledge” Peter distinguishes true, saving knowledge from the speculative claims of false teachers (2 Peter 2:20). Genuine knowledge: 1. Is granted “by His divine power” (1:3). 2. Leads to moral excellence (1:5-8). 3. Guards against doctrinal error (3:17-18). This knowledge grows through Scripture (Psalm 119:104; 2 Timothy 3:16-17) and the illumination of the Spirit (John 16:13). Integrated Concept: Dynamic Spiritual Maturation Grace without knowledge can drift into permissiveness; knowledge without grace can harden into pride. The Spirit welds them together in sanctification (2 Thessalonians 2:13). Growth is therefore: • God-energized—“it is God who works in you” (Philippians 2:13). • Human-responsible—“make every effort” (2 Peter 1:5). • Community-oriented—imperative is plural; disciples sharpen one another (Hebrews 10:24-25). Apostolic Imperative vs. Indicative The command rests on an accomplished indicative: “our Lord and Savior Jesus Christ.” Because Christ is both sovereign (“Lord”) and redeemer (“Savior”), growth is not self-improvement but response to His supremacy. The closing doxology (“To Him be the glory”) frames all growth as worship. Contrast with False Teachers False teachers “promise them freedom, while they themselves are slaves of depravity” (2 Peter 2:19). They regress; believers progress. They deny the Master; believers deepen in grace provided by Him. Growth therefore safeguards from “error of the lawless” (3:17). Means of Growth 1. Scripture: “Like newborn babies, crave pure spiritual milk” (1 Peter 2:2). Early papyrus P⁷² (3rd cent.) contains both Peter and Jude, confirming the stable text that nourishes believers. 2. Prayer: “Let us then approach the throne of grace” (Hebrews 4:16). 3. Fellowship: “Devoted to the apostles’ teaching … and the prayers” (Acts 2:42). 4. Ordinances: Baptism and the Lord’s Supper tangibly rehearse grace and knowledge (Romans 6:3-4; 1 Corinthians 11:26). 5. Suffering: Trials refine faith (1 Peter 1:6-7), forcing reliance on grace and pushing believers into deeper knowledge of Christ’s sufferings (Philippians 3:10). Role of the Holy Spirit The Spirit is “the Spirit of grace” (Hebrews 10:29) and “the Spirit of truth” (John 14:17). He distributes gifts (1 Corinthians 12:4-11), teaches (1 John 2:27), bears fruit (Galatians 5:22-23), and seals believers “for the day of redemption” (Ephesians 4:30). No growth bypasses His indwelling ministry. Grace and Knowledge in Salvation and Sanctification Salvation: Grace initiates; knowledge of Christ brings faith (Ephesians 2:8; Romans 10:17). Sanctification: Grace empowers; knowledge directs (Titus 2:11-12; Colossians 1:9-10). Glorification: Future grace completes growth (1 Peter 1:13). “We know that when He appears, we will be like Him” (1 John 3:2). Christological Center “Of our Lord and Savior Jesus Christ” fixes the object of growth. Peter’s earlier eyewitness testimony of the Transfiguration (1:16-18) underscores Christ’s majesty and validates the command. Apostolic proclamation hinges on the historical resurrection (Acts 2:32); growth is relational with the living Christ, not a deceased teacher. Eschatological Orientation “To the day of eternity” anchors perseverance. As scoffers deny future judgment (3:4), believers live in forward-leaning holiness (3:11-12). Continuous growth prepares the church for the Lord’s imminent return. Historical Witness Early fathers echo the exhortation: • Irenaeus, Against Heresies 4.9.2—speaks of believers “receiving more and more grace” as they walk with Christ. • Origen, Commentary on John 32.17—argues knowledge of the Son advances progressively. Manuscripts such as Codex Vaticanus (B) and Sinaiticus (ℵ) preserve 2 Peter 3:18 intact, attesting textual stability across geographical lines. Practical Implications for Believers Today Behavioral studies of habit formation reveal growth occurs through incremental, repeated practice. Spiritual disciplines correspond to “trigger-routine-reward” cycles, directing affections toward Christ and reshaping neural pathways (Romans 12:2). Grace provides motivation free from performance anxiety; knowledge supplies content that guides transformation. Application in Church Life Pastoral teaching, catechesis, and discipleship curricula should systematically expand both doctrinal knowledge and lived grace. Metrics of success shift from numerical growth alone to observable fruit—love, joy, peace, and doctrinal soundness. Conclusion: Doxological Purpose The imperative to “grow in the grace and knowledge” culminates in worship: “To Him be the glory both now and to the day of eternity.” Growth exists for God’s praise. As believers flourish in grace and deepen in knowledge, the splendor of Christ shines ever brighter through them, until the eternal day when faith becomes sight and growth reaches its God-appointed goal. |
