Thru the Bible in a Year
Today we step into the last three chapters of Ephesians—chapters that shift the focus from who we are in Christ to how we live because of Christ. Paul has spent the first half of the letter unveiling the breathtaking riches of our salvation, describing our position in Christ, and revealing God’s eternal plan for His people. Now, beginning in Ephesians 4, Paul transitions to the practical outworking of that salvation. If the first half of the letter tells us what God has done for us, the second half tells us how we now walk in response. And because this reading falls during Advent—a season of preparation—it serves as a timely reminder that discipleship is not only about believing rightly but walking faithfully.
Paul uses the word walk repeatedly in these chapters, reminding us that the Christian life is not static; it is movement, journey, growth. Salvation is not merely an event but a new way of living, a reshaping of our relationships, values, habits, and conduct. As John Stott once noted, “Nobody can maintain a justified status without sanctified behavior.” What we believe must shape how we behave. This beautiful balance—grace received, grace expressed—stands at the center of Ephesians 4–6.
Paul begins with a call to “walk properly,” highlighting three themes: concord, callings, and contrast. First, he calls us to concord, urging believers to walk in humility, gentleness, patience, and love in order to preserve unity. Unity is not uniformity; it is the shared life of the Spirit that binds believers together in Christ. Paul insists that this unity must be guarded, nurtured, and expressed through gracious conduct. In a world marked by division, discord, and self-promotion, this unity becomes a powerful testimony of Christ’s presence among us. Advent reminds us that Jesus came to bring peace—not only peace with God, but peace among His people.
Paul then moves to callings. Every believer has been given a place in the Body of Christ. He describes Christ giving the church apostles, prophets, evangelists, pastors, and teachers—all for the purpose of equipping the saints for ministry and building spiritual maturity. One of the glories of Ephesians is that it does not limit ministry to clergy; every believer is called, gifted, and commissioned. The diversity of these callings is intentional, designed by God to strengthen the whole Body and propel it toward spiritual growth. As commentator F. F. Bruce observed, “The church is healthiest not when its leaders perform all the ministry but when they train the members to fulfill their God-given service.” We grow when we serve, and we serve because God equips us to serve.
The third theme is contrast. Paul draws a sharp distinction between the life of believers and the life of the Gentile world. He names specific sins that must not characterize God’s people—lying, destructive speech, greed, immorality, bitterness, malice. While this list may feel uncomfortable, Paul frames it not as legalism but as liberation. To follow Christ is to step out of the shadows of our former lives and walk in the light. He reminds believers not to partner with the “unfruitful works of darkness,” for companionship shapes character. Instead, believers are called to expose and renounce evil—to “reprove” it—not through harshness but through the steady radiance of a holy life. Advent teaches us that Christ came as the Light who shines in the darkness; therefore, those who follow Him must walk as children of light.
Paul then directs us to “walk prudently,” focusing on relationships. Christianity is never lived in isolation. It touches marriages, families, workplaces, and communities. Paul speaks first to husbands and wives. The wife is called to respect and submit to her husband, and the husband is called to love his wife sacrificially—as Christ loved the church. Paul’s vision of marriage is not about dominance but devotion; not coercion, but Christlike love. The husband’s calling is extraordinarily demanding, for the reference point is Calvary—a love that gives, protects, and cherishes. Advent reminds us that love came down to us, and in marriage, that love is meant to be mirrored within the covenant of two becoming one.
Paul then addresses parents and children. Children are called to obey their parents in the Lord, but Paul also cautions fathers not to provoke their children through harshness or inconsistency. Parenting, Paul reminds us, is authority balanced by tenderness—discipline guided by the heart of God. As we move toward Christmas, a season filled with family gatherings, this reminder becomes especially relevant. God calls us to create homes where His peace can dwell, His Word can be taught, and His love can be experienced.
Paul’s final relational instruction concerns masters and servants. Though the context is ancient, the principle extends into modern workplaces. Those under authority are called to serve with sincerity, as unto the Lord, and those in authority are called to treat others with fairness and compassion. In every relationship—marriage, parenting, work—Paul invites us to demonstrate Christ’s character. Our walk with God is validated by the way we treat others.
The final section turns to the call to “walk powerfully.” Paul knows that Christian conduct does not happen in a vacuum; we walk through spiritual opposition. Behind the visible world lies a realm of spiritual warfare. Paul identifies the adversary—the devil—and outlines the battleground: principalities, powers, rulers of darkness, and spiritual wickedness in high places. These enemies are real, persistent, and strategic. Yet Paul does not leave us unprotected. He describes the armor of God: truth, righteousness, peace, faith, salvation, and the Word of God. Each piece reflects the character of Christ Himself. When we put on the armor, we are putting on Christ.
This armor is not ornamental; it is essential. The Christian life cannot be lived victoriously without the equipment God supplies. Paul ends the section with an appeal—to pray at all times, in all situations, for all believers. Prayer is not an optional accessory to the armor; it is the atmosphere in which the armor functions. Prayer sustains, guides, empowers, and aligns us with God’s will. Paul himself asks for prayer, reminding us that even the strongest servants of God stand only by His grace.
As we reflect on Ephesians 4–6 during this Advent season, we are invited to examine how we walk. Are we walking in unity? In our calling? In holiness? In wisdom within our relationships? In spiritual strength? Paul’s words encourage us that, by the Spirit’s power, we can. The same Savior whose birth we celebrate at Christmas is the One who strengthens our steps today.
Thank you for committing yourself to the daily study of God’s Word. Scripture assures us that His Word will not return void but will accomplish what He desires in your life. Continue walking faithfully through this year-long journey, knowing that every step brings you deeper into the heart of God.
