The sermon continues an expository series in 1 Peter, picking up from the previous week's study of Christian identity as "sojourners and exiles" in the world. The preacher briefly recaps four convictions established earlier: believers' primary citizenship is in heaven, not in any earthly nation; their supreme constitution is Scripture, not any civil law; their ultimate king is Christ alone, not any political ruler; and their deepest longing is for heavenly treasure, not the passing things of this world. Abraham and Moses are held up as examples of this pilgrim identity — both spent their lives without ever permanently possessing the promised land, yet Moses could still declare in Psalm 90 that the Lord himself, not any place, was his true "dwelling place." The sermon argues that this sojourner identity flows directly from being born again by God, and turns to 1 Peter 1:3–4 to explore what that new birth actually means.

Drawing on Anthony Hoekema's definition, the sermon describes regeneration as the Spirit's work of uniting a person to Christ and renewing the heart, so that someone spiritually dead becomes spiritually alive and is thereby enabled and willing to repent, believe the gospel, and serve God. Three questions structure the rest of the message. First, what causes new birth? The sermon insists, against a common misunderstanding, that regeneration is not the result of believing in Christ but its cause — "faith is the fruit, not the root of being born again." Just as 1 Peter 1:3 begins "in his great mercy he has caused us to be born again," so 1 John 5:1 and Ephesians 2:4–5 teach that God, being rich in mercy, made spiritually dead sinners alive together with Christ before and as the ground of their believing. Since everyone since Adam is dead in sin, no one can respond to the gospel apart from the Spirit first regenerating the heart. The sermon illustrates this unmerited mercy with a topical aside on Queen Camilla's transformation in public perception from "most hated woman in Britain" to "the redeemed one" at King Charles's coronation, likening it to how believers are loved by God not because they are lovable but purely because he is merciful.

Second, how does new birth happen? The sermon turns to 1 Peter 1:23–25: believers are born again "not of perishable seed but of imperishable, through the living and abiding word of God" — the gospel itself is described as "the seed of regeneration." When the true gospel is preached and heard, the Spirit plants this seed and gives new life, which is why faithful proclamation of the authentic gospel (not a false one) remains essential and can transform even those who have lived for decades without knowing God.

Third, how can believers know they have been born again? The sermon draws an analogy to physical birth: just as one knows one is alive by breathing and living, one knows one is spiritually reborn by spiritual life and evidence of change. Three marks are named. The first is the capacity and willingness to believe in Christ (John 1:12–13) — this faith is itself a sign of being born of God, not a human achievement. The second is a life marked by purification and obedience rather than continuing habitually in sin (1 Peter 1:22; 1 John 3:9–10). The sermon carefully corrects a mistranslation in the Indonesian Bible that implies the regenerate "cannot sin at all," clarifying from the NIV that the sense is one "will not continue to sin" — the regenerate still fall, as David, Peter, and the prophets did, but they do not remain comfortable in sin; they respond to conviction with genuine repentance, as David did when confronted by Nathan, rather than resenting correction or seeking out churches that never address sin. The third mark is genuine, sacrificial love for fellow believers "deeply from the heart" (1 Peter 1:22; 1 John 4:7), modeled on Christ's love for the church in giving himself to sanctify and present her without blemish (Ephesians 5:25–27). Because believers are one body in Christ, loving one another is described as also serving one's own good, while hatred or gossip functions like an autoimmune disease attacking the body from within.

The sermon closes by noting that Peter frames all this doctrine within praise — "Blessed be God" — arguing that sound teaching about God's mercy should move the heart to worship, not merely inform the mind, and closes with practical exhortations toward punctual, wholehearted corporate worship as an outworking of this new birth.
