The sermon continues a verse-by-verse exposition of Ephesians, dwelling on the greeting of Ephesians 1:1-2: "Paul, an apostle of Christ Jesus by the will of God, To the saints who are in Ephesus... Grace to you and peace from God our Father and the Lord Jesus Christ." The preacher opens with a personal story: after the previous week's sermon on God's moral will, his son asked a probing question at home about how "do not be anxious" (Matthew 6) counts as God's moral will rather than merely a comforting promise. Working through that question together, the preacher argues, illustrates why personal interaction with the Word — asking, discussing, applying it at the family table — cements truth far more deeply than passive listening. He urges the congregation to keep talking about the sermon after the service, since everyone hears with a different angle and experience.

Turning to the text, the sermon frames Paul's greeting as an "overture" — in the way an overture in music states the main themes that will be developed later in the piece. Ephesians' introduction, though brief, already contains the themes the letter will unfold in full: grace and peace.

On grace, the sermon draws on Paul's words in 1 Corinthians 15:10, "By the grace of God I am what I am," to argue that grace is the most basic and foundational reality of the Christian life — like a wellspring from which everything else flows; without it, the river runs dry. Grace is distinguished from ordinary human love: worldly love is a "love because" (I love you because you are good, beautiful, lovable), whereas grace is a "love despite" — God loves and gives grace to sinners despite their rebellion. Romans 5 is invoked to show that Christ died for us "while we were still sinners," still enemies of God who dishonored and disregarded him. The sermon calls this unmerited or undeserved favor, contrasted with what we actually deserve: God's wrath. Ephesians 2 is cited for the truth that we were by nature children of wrath, yet instead of pouring out wrath on us, God poured it out on the sinless Christ, who bore our sin so that those in Christ receive grace rather than judgment. The sermon further distinguishes mercy from grace as two sides of one coin: mercy is God withholding the punishment we deserve; grace is God giving the blessing we do not deserve.

Grasping this grace, the preacher insists, requires first grasping the depth of our own sin — illustrated through the parable of the unforgiving servant, forgiven a debt of 10,000 talents yet unwilling to forgive a debt of 100 denarii. A servant who does not recognize the size of the debt he has been forgiven will not extend mercy to others; failing to recognize grace leaves life unchanged. Conversely, when Paul recognizes grace, he does not boast in his own labors ("I worked harder than any of them") but immediately corrects himself: "it was not I, but the grace of God that is with me." Grace produces effort and obedience, not passivity — the preacher applies this directly to the congregation's calling to sacrificial church-planting work in the coming year, framing perseverance in obedience as itself an experience of further grace. He also addresses the opposite danger: believers who conclude their sin is too great to be forgiven, which the sermon calls a subtle form of pride, since it makes personal sin greater than the grace of God. Scripture and hymnody both affirm that "the grace of God is greater than all our sin," and that the only qualification for receiving it is to come empty-handed, aware of one's spiritual bankruptcy. The incarnation itself — the Creator of the universe entering the smallness of the world, as John Calvin's line is quoted, "the Son of God became the Son of Man, so that the sons of men might become the sons of God" — is presented as the supreme expression of this grace.

The second theme, peace, is described as the river that flows from the spring of grace. Peace was ruptured by sin: relationship with God, with others, and within oneself was broken beginning at the Fall (Genesis 3), escalating through the first murder (Genesis 4) and spreading violence (Genesis 6). The sermon connects this brokenness to present-day wars (Gaza, Ukraine) and to hostility within families, arguing that all such conflict traces back to enmity with God. Ephesians 2:13-14 is read at length: Christ himself is "our peace," who breaks down the dividing wall of hostility — historically between Jew and Gentile, and by application between any two peoples reconciled through the cross, illustrated by an anecdote of enemy soldiers recognizing each other as Christians through a shared hymn whistled in the field and embracing instead of fighting. Because Christ has forgiven so much, believers are called to forgive one another and to test the genuineness of their love for God by their love for fellow believers, echoing 1 John. Philippians 4 is cited for "the peace of God which surpasses all understanding," guarding hearts and minds in Christ Jesus — a peace not dependent on external calm but present even amid suffering, illustrated by Jesus calming the storm and asking the disciples, "Why are you afraid?"

Finally, the sermon turns to the identity grace and peace confer: believers are called "saints," a word properly rendered "holy" (set apart) rather than "pure," since holiness first denotes status — being set apart as God's own possession — before it denotes ongoing moral transformation. The sermon notes that early manuscripts of Ephesians omit "in Ephesus," suggesting the letter was a circular letter addressed simply "to the saints" everywhere, reinforcing that sainthood belongs to all believers, not a select few as in Roman Catholic canonization. Believers, having put off the old self, are now called to the ongoing, progressive work of sanctification — being continually renewed in mind, speech, and will — while resting in the assurance that nothing can separate them from God's love, since he who began this good work will complete it.
