The sermon continues a series through Ephesians, working through chapter 4, verses 3 through 6, and frames the whole book around the question Francis Schaeffer made famous: "How should we then live?" Having spent chapters 1 through 3 establishing rich doctrinal truths — who God is, who Christ is, what Christ has accomplished, and how believers were chosen before the foundation of the world — Paul now turns, from chapter 4 onward, to the practical outworking of that doctrine. The preacher notes that forty of the letter's forty-one imperatives fall in chapters 4 through 6, underscoring that sound doctrine must issue in a life worthy of the calling received.

The first command taken up is Ephesians 4:3, "make every effort to keep the unity of the Spirit through the bond of peace." The sermon situates this command against the deep hostility between Jew and Gentile in Paul's day, drawing a contemporary parallel to ongoing enmity in the Middle East — Israel, Iran, Palestine — as a picture of how humanly impossible such unity seems. That two historically hostile peoples could sit at one table, the preacher says, is something the modern imagination can only stage as an AI-generated joke; yet this is precisely the miracle the gospel accomplishes, and precisely what God commands the church to guard.

The sermon works through several dimensions of what "the unity of the Spirit" means. First, drawing on Ephesians 2:18 and 1 Corinthians 12:3, it is a unity created by the Holy Spirit, not manufactured by human effort — it is the Spirit who grants both Jew and Gentile access to the Father, and only by the Spirit can anyone confess "Jesus is Lord." Because this unity is the Spirit's own work, the command in verse 3 is to keep or maintain it, not to create it: believers steward a unity that already exists as objective spiritual reality. Second, appealing to Ephesians 2:22, the substance or content of this unity is the Spirit himself, indwelling every believer and binding them together from within. Third, drawing on Galatians 5:22-23, this unity is preserved by the fruit the Spirit produces — love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control, described as one fruit bearing nine flavors. Where those fruits are present among believers, unity becomes visible and real.

Returning to the command itself, the sermon stresses the intensity of "make every effort" — not merely making an effort but making every effort, straining with deliberate, costly diligence. This unity cost God dearly: citing Ephesians 2:13, 15, and 16, the preacher traces how the blood of Christ, his death, and the cross itself abolished the hostility between Jew and Gentile and created one new humanity, giving true peace — not a mere ceasefire that could collapse at the next provocation, but genuine reconciliation. Paul lists seven "ones" in verses 4-6 (one body, one Spirit, one hope, one Lord, one faith, one baptism, one God and Father of all) as objective realities that are nonetheless not yet fully experienced; this creates ongoing tension the church must labor within, since perfect harmony will not be realized this side of eternity, as Ephesians 1:18 makes clear in Paul's prayer that believers' hearts be enlightened to grasp this hope.

The sermon presses this personally and pastorally, acknowledging real friction within the congregation and within families — spouses, siblings, parents and children who avoid or resent one another. Illustrating costly perseverance, the preacher recounts a widely reported rescue involving a Lithuanian adventurer trapped by the foot in a rushing, freezing river for over twenty-four hours, with rescuers making every conceivable effort — even contemplating amputation — before he could be freed, as an image of the relentless, sacrificial effort the command to "make every effort" demands.

Citing a pastor named Scott Hubert, the sermon warns that churches are destroyed not only by visible conflict — anger, criticism, troublemaking — but subtly and more dangerously by "ice": passive, individualistic believers who neither offend nor engage, treating church membership like a gym membership rather than a family bound together as the body of Christ. Both patterns — fire and ice — corrode unity. The sermon closes by urging the congregation to actual, costly obedience: naming specific relationships that need mending, applying this in small groups, and echoing Jesus's own call in Matthew 5:29-30 to remove whatever must be sacrificed rather than let it destroy fellowship, so that the world may know Christ's disciples by their love for one another.
