“Grace and peace be yours in abundance through the knowledge of God and of Jesus our Lord.” (2 Peter 1:2, New International Version)
Simon Peter begins his letter with a powerful greeting—grace and peace multiplied through knowledge. Indeed, spiritual maturity begins with intimate relationship and understanding. Peter does not call for abstract philosophical speculation, but experiential, relational knowledge—Greek epignosis—a deep, personal acquaintance with the Savior. This isn’t mere head knowledge, but spiritual intimacy, as one would know a trusted friend or beloved family member.
As Western Christians, we often associate knowledge with intellectual understanding, but in the Hebraic-Jewish tradition in which Peter was formed, knowledge implied responsibility and practical application. Peter invites us not simply to learn facts of theology, but to walk daily with Christ himself.

Peter makes an astonishing proclamation: God has granted us everything necessary for “life and godliness,” allowing us to share in His divine nature (2 Peter 1:3–4). This phrase—“participate in the divine nature”—is bold and profound. The church father Athanasius famously remarked, “He became man so that we might become gods” (On the Incarnation). This does not mean we become equal to God in essence; rather, it indicates that we are graciously drawn into real fellowship with God’s holiness, purity, and love. Peter emphasizes the transformative power of God that draws us away from corruption and enables believers to live godly lives.
Historical theologians such as John Calvin observed that this “participation” refers primarily to our restoration in God’s image—moral perfection, righteousness, holiness, and communion with God—which was marred by human rebellion in Eden. Peter’s promise is not distant; it begins the moment we embrace Christ and continues to grow as we depend on God’s power and promises.

Peter lays out for us a spiritual “ladder,” adding virtue upon virtue: faith, goodness, knowledge, self-control, perseverance, godliness, brotherly kindness, and love (2 Peter 1:5–7). Here, there is a culturally embedded concept of progressive moral development (similar to Stoic lists found in Greek ethics), but with a distinctively Christian end goal: genuine love. For Western Christians accustomed to viewing growth as instant and self-driven, Peter’s perspective proves humbling: these qualities grow gradually, interconnectedly, and only through reliance upon God’s grace.
Peter emphasizes that if we nurture these spiritual virtues, we will be fruitful in the “knowledge of our Lord Jesus Christ” (verse 8). Conversely, negligence leads to spiritual blindness—having lost sight of the gospel’s transforming power (verse 9). The ancient Hebrews would have deeply valued this imagery of sight versus blindness, a metaphor for spiritual discernment often used by prophets and apostles alike.
Cross-reference: Galatians 5:22–23; Philippians 4:8; Hebrews 12:1–2.
Finally, Peter underscores the reliability of the apostles’ testimony, recounting the eyewitness experience of Christ’s glory on the Mount of Transfiguration (v.16–18; cross-reference Matthew 17). The term Peter uses for “eyewitnesses” (Greek: epoptai, meaning eyewitnesses or privileged observers) suggests someone who personally witnessed an event of religious significance, commonly used in the Greek mystery religions. Peter explicitly distinguishes apostolic witness from “cleverly devised myths,” common in first-century religious narratives. Against such mythical traditions, Peter firmly grounds Christian truth in historical experiences verified by multiple witnesses.
Furthermore, Peter draws our attention to Scripture transformed into something even more “sure” (v. 19–21). He affirms the divine inspiration of prophetic scriptural writings, stressing their divine rather than human origin. The Holy Spirit guided the biblical prophets, making Scripture authoritative and trustworthy—even surpassing personal experience and eyewitness observation. History’s greatest theologians, from Augustine to Luther to Wesley, echoed this essential truth: Scripture is our reliable guide, illuminated by the Holy Spirit, leading us towards maturity in Christ.
Cross-reference: 2 Timothy 3:16–17; Psalm 119:105; Matthew 17:1–8.
“Be Thou My Vision” (traditional Irish hymn), which beautifully expresses dependence upon the wisdom, strength, and guidance of Christ alone, complements this chapter’s call for growth and intimacy with God.
As we meditate on Peter’s words today, let us renew this commitment: to pursue deeper personal knowledge of Christ, actively grow in spiritual virtues, and constantly affirm the trustworthiness of God’s inspired Word. Spiritual maturity is not automatic; it requires intentional cooperation with the grace of God poured abundantly into our lives through our intimate relationship with Christ.
Heavenly Father, thank You for the precious promises that You have given us in Christ Jesus, enabling us to share in Your divine life and holiness. Deepen our knowledge and love for Christ. Help us grow diligently in the virtues that reflect Your glory, and may we always stand firmly rooted in the truthfulness and authority of Your Word. By Your Spirit, illuminate Your Scriptures to us and lead us continually towards spiritual maturity. In Jesus’ holy name, Amen.
