Introduction: Ephesians 4 and David Jang’s Emphasis
The fourth chapter of Ephesians stands as one of the most critical New Testament texts in formulating our understanding of the church. In this single chapter, the Apostle Paul speaks profoundly about the unity and diversity of the body of Christ, the growth and maturation that the church must undergo, and the ultimate goal of reaching “the measure of the stature of the fullness of Christ” (Eph. 4:13). This text also weaves together the individual believer’s spiritual maturity and the organic union of the entire Christian community, reminding us that both personal sanctification and corporate edification go hand in hand. Furthermore, it highlights an eschatological hope that propels the church toward its destiny in God’s plan of redemption.
When David Jang interprets Ephesians 4, he does not merely keep the discussion on a theoretical or doctrinal level. Rather, he seeks to bring the text’s exhortations into practical application for contemporary believers. One will find, in his expositions, numerous reflections on the present-day realities of church life—its successes, struggles, and persistent challenges. He emphasizes that the commands in Ephesians 4—“be one,” “grow to maturity,” “do not be tossed about by every wind of doctrine”—are not abstract ideas reserved for first-century Christians alone but pressing and immediate imperatives for every age. The church’s calling, in his words, is to become a dynamic, unified, and mission-focused community that stands as the “vanguard” (or “front guard”) of God’s kingdom here on earth.
In examining this passage through David Jang’s lens, five major themes emerge:
- Church unity and diversity – how these realities intertwine as a dynamic balance.
- Faith and knowledge – why these must be held together for genuine spiritual maturity.
- Growth and spiritual maturity – the idea of the church as an organism that constantly grows, rather than a static institution.
- Love as the core of unity – how the church grows only through “speaking the truth in love” (Eph. 4:15) and being “knit together” (4:16).
- Discernment in the face of worldly influences – the necessity of avoiding the “winds of doctrine” and “cunning craftiness” that threaten to deceive believers.
These five themes, David Jang affirms, form an interconnected whole: the church experiences unity in the midst of diversity, enriched by both faith and knowledge, culminating in a corporate maturity undergirded by love, and sustained by diligent discernment amid worldly philosophies. What follows is a detailed exploration of each theme, incorporating the broader context of Ephesians 4 while integrating David Jang’s pastoral and theological insights. Through this extended exposition—totaling around 6,500 words—readers will gain a fuller understanding of how Ephesians 4 can profoundly shape the life, mission, and future hope of the church.
1. Church Unity and Diversity—A Living Tension in Ephesians 4
1.1. The Body of Christ as a Paradigm of Unity
Ephesians 4:4–6 reads: “There is one body and one Spirit—just as you were called to the one hope that belongs to your call—one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all.” This bold declaration frames the foundation of the church’s unity, pointing to its Trinitarian source: the one Spirit, the one Lord (Christ), and the one God and Father. According to the Apostle Paul, the very nature of God—triune and yet one—becomes the model for how the church should understand its unity.
David Jang often underscores that this oneness of the church does not stem from human consensus or organizational efficiency. It is not unity born of a corporate structure, nor of groupthink, nor of mere uniformity in cultural or social practices. Instead, it is a unity that flows from the divine life of the Triune God, manifested in the incarnation, death, and resurrection of Jesus Christ. In Acts 20:28, Paul reminds the Ephesian elders that Jesus purchased the church “with His own blood.” David Jang cites this verse to stress how the costly sacrifice of Christ becomes the powerful unifying force among believers.
1.2. Diversity of Gifts and the Organic Nature of the Church
Yet, this same passage in Ephesians 4 does not merely insist on a monolithic view of the church. After exhorting believers to maintain unity, Paul immediately delves into the realm of diversity: “But grace was given to each one of us according to the measure of Christ’s gift” (Eph. 4:7). Verse 11 reveals that “He gave the apostles, the prophets, the evangelists, the shepherds and teachers…,” emphasizing the variety of ministries within the body. No single member can claim all roles, nor can any local church group expect everyone to serve in exactly the same way.
For David Jang, this tension between unity and diversity is a “dynamic equilibrium.” On one side is the fundamental oneness of the body, united under Christ; on the other side is a symphony of gifts and callings, each believer contributing distinctively to the welfare of the church. Citing the body metaphor in 1 Corinthians 12:12–27, Jang insists that the concept of “church as an organism” is far more than a simple metaphor. It expresses the actual spiritual reality that each member is interconnected and interdependent. Just as various organs and cells in a human body perform unique tasks yet function together for the life of the whole, so too in the church, diverse gifts work in concert for the overall good.
He points out that diversity of gifts requires humility and responsibility. If one has a strong teaching gift, that person must not look down on those with a different calling; likewise, those with more “behind-the-scenes” gifts must not belittle themselves or assume they are unimportant. The church can only thrive when each part operates under the lordship of Christ, oriented towards mutual edification (Eph. 4:12). David Jang perceives one of the great threats to this diversity-based unity as a misunderstanding of spiritual gifts—where some gifts are exalted to an elite status while others are deemed inferior. He warns that the result of such an imbalance is division, envy, or negligence, ultimately undermining the church’s collective mission.
1.3. Growing Together: The Mustard Seed and Leaven Principles
David Jang loves to allude to the parables in Matthew 13: the mustard seed and the leaven. Though these parables are not explicit in Ephesians 4, he views them as apt illustrations of the organic, gradual, and at times subtle manner in which the church grows as one organism. The mustard seed, the smallest among seeds, sprouts into a tree where birds find shelter. The leaven, though hidden in three measures of flour, permeates the entire batch.
This parallels the church’s growth pattern: it may begin in a small, seemingly insignificant way—like a mustard seed—but over time, it expands and offers refuge. Similarly, like leaven, the influence of the gospel and the Spirit of Christ works invisibly to transform the entire “dough” of the church, and even the world. In each case, unity does not imply stasis or uniformity but a living process of expansion and integration, all guided by the Holy Spirit.
2. The Integration of Faith and Knowledge
2.1. The Apostolic Charge in Ephesians 4:13
Ephesians 4:13 exhorts believers “until we all attain to the unity of the faith and of the knowledge of the Son of God…” Here, Paul ties together two critical components: faith (pistis) and knowledge (gnōsis). Often, Christian spirituality is portrayed in a dichotomous way: some emphasize “heart faith” that spurns intellectual rigor, while others idolize theological knowledge at the expense of relational trust in Christ. For David Jang, there is no need to pit these against each other; rather, biblical maturity requires both.
He explains that faith is the gracious response to God’s revelation—an opening of one’s heart to the redemptive work of Jesus. In his expositions on Galatians 3, David Jang reiterates that faith is not self-generated. It is awakened by the preaching of Christ, nurtured by the Holy Spirit, and grounded in a personal encounter with God’s love. This faith, then, cannot remain static; it must be further deepened by knowledge.
2.2. The Hebrew Conception of ‘Knowing’ (yada)
David Jang often clarifies that in Hebrew thought, “to know” (yada) carries a sense of intimacy, covenant relationship, and experiential awareness, rather than mere cerebral understanding. Thus, to “know” Jesus involves encountering Him in His Word, in prayer, in worship, and in the life of the church, where His presence is actively at work. It is akin to how Adam “knew” Eve (Gen. 4:1), not just as a conceptual recognition, but as a deep, personal union. In the spiritual realm, to truly know Christ is not just to memorize theological facts; it is to be transformed by an ongoing relationship with Him.
2.3. Avoiding the Pitfalls of Extremes
If a believer settles for blind enthusiasm without grounding in Scripture and sound doctrine, the result can be fanaticism or a shallow emotionalism that withers under trials. Conversely, if knowledge is amassed without vibrant faith, the believer can become puffed up with pride or trapped in intellectual debates devoid of love. David Jang therefore insists on a balanced approach: “faith and knowledge” must be woven together into a tapestry of holistic Christian living. This unity of faith and knowledge propels the church toward greater maturity and helps guard against the false teachings that Paul warns about in Ephesians 4:14.
2.4. Practical Outworking in the Church
In practical terms, David Jang encourages every church to foster systematic Bible study, robust theological education (including exposure to confessional standards such as the Apostles’ Creed or the Nicene Creed), and ongoing discipleship programs that deepen believers’ understanding of Scripture. Simultaneously, he calls for fervent worship, intercessory prayer, and the cultivation of a living relationship with God—ensuring that what is learned intellectually becomes a matter of the heart, producing obedience and love. In this way, the church as a whole moves closer to “the measure of the stature of the fullness of Christ.”
3. The Church’s Growth and Spiritual Maturity
3.1. The Nature of Growth: A Gradual Yet Purposeful Process
In Ephesians 4:14–16, Paul paints the image of a growing and maturing church. The passage contrasts spiritual infancy—where believers are easily led astray by false teachings—with the goal of mature adulthood in Christ. David Jang asserts that one of the greatest tragedies in contemporary Christianity is that many remain in a perpetual state of spiritual childhood. They may profess faith but have not pressed on to maturity (cf. Heb. 5:12–14). Lack of deep biblical knowledge, insufficient commitment to prayer and fellowship, or a purely consumerist approach to church can stall believers at an infantile stage.
However, the apostle’s vision is clear: “so that we may no longer be children” (Eph. 4:14). The church must relentlessly pursue spiritual adulthood. David Jang describes this as a “holy dissatisfaction” with the status quo. Just as physical growth is the natural trajectory for a child—barring any health issues—so spiritual growth should be the normative process for every believer. It is neither optional nor peripheral; it is central to our identity as disciples of Christ.
3.2. The Role of Doctrine and Teaching in Growth
A key aspect of this growth is solid teaching. David Jang underscores that doctrinal clarity serves as the “skeleton” upon which the spiritual life is built. Just as a child’s bones need proper nutrition to grow, believers need the “meat” of Scripture, biblical theology, and Christian doctrine. This does not mean incessant academic debate for its own sake. Rather, it means grounding one’s life in the revealed truth of God, allowing Scripture to shape worldview, ethics, and worship.
Church leaders—pastors, elders, small group leaders—carry a particular responsibility here. Quoting Ephesians 4:11–12, David Jang stresses that the gifts of apostles, prophets, evangelists, shepherds, and teachers are “to equip the saints for the work of ministry, for building up the body of Christ.” When leaders faithfully teach and model the Word, the congregation can move from spiritual milk to solid food, discerning God’s will amidst the ever-changing values of the surrounding culture.
3.3. Spiritual Disciplines and the Empowerment of the Holy Spirit
In addition to teaching, David Jang highlights the role of spiritual disciplines—prayer, fasting, personal devotion, worship, and sacramental life. He repeatedly references the necessity of “reliance on the Holy Spirit,” who alone can effect genuine inward transformation. While the mind receives instruction, the Spirit animates and applies that truth to the heart.
The synergy of the Word and the Spirit, in David Jang’s theology, prevents the church from devolving into either dead orthodoxy or unhinged emotionalism. The Spirit brings the living power of God’s grace to bear on the truths of Scripture, sparking conviction, repentance, joy, and perseverance. This fosters a form of growth that is comprehensive: believers begin to exhibit the fruit of the Spirit (Gal. 5:22–23) and develop gifts for service (Rom. 12; 1 Cor. 12–14), all aimed at the edification of the body.
3.4. Corporate and Individual Dimensions of Maturity
Though Ephesians 4 speaks of “we all” coming to maturity, it still respects the individuality of each believer. David Jang interprets the text as emphasizing both personal and communal development. On the one hand, each believer must personally cultivate faith, prayer, and Scripture study. On the other hand, the church as a collective entity is more than the sum of its parts. The Holy Spirit knits together believers through shared worship, service, accountability, and mutual edification.
David Jang often notes that the Greek phrase in Ephesians 4:16, translated “joined and held together by every joint with which it is equipped,” stresses the synergy of every connection in the body. Growth does not happen in isolation; it is corporate, relational, and interdependent. The global church, likewise, can learn from diverse traditions and expressions within the body of Christ, provided they remain anchored in the apostolic gospel and in the confession of Christ’s lordship.
4. Love as the Bond of Unity and Growth
4.1. Speaking the Truth in Love (Ephesians 4:15)
One of the most memorable phrases in Ephesians 4 is “speaking the truth in love.” David Jang regards this as a cornerstone for understanding how the church grows into Christlikeness. Truth, divorced from love, can become harsh or legalistic. Love, absent truth, devolves into sentimentality or moral compromise. Only when truth and love converge does the body truly build itself up in maturity.
Jang connects “speaking the truth in love” to the entire biblical narrative. From the Old Testament prophets, who bravely spoke God’s words out of deep concern for Israel’s spiritual welfare, to Jesus’ own ministry, in which He exemplified compassion toward sinners while never compromising the demands of holiness—love and truth have always been inseparable. Therefore, in the life of the local congregation, confrontation and correction must occur in the context of genuine care; building up must occur without flattery or deceit. This is the biblical pattern for healthy relationships, counseling, discipleship, and leadership within the church.
4.2. The Vision of Ezekiel 37 and Ephesians 4:16
David Jang likes to draw a parallel between Ezekiel 37—where the prophet witnesses dry bones coming together, gaining flesh and breath—and Ephesians 4:16, which describes how “the whole body, joined and held together by every joint … grows so that it builds itself up in love.” In Ezekiel’s vision, the disjointed bones represent Israel’s hopeless condition, but God’s Word and Spirit bring the bones together to form an exceedingly great army. Jang sees in this a prophetic illustration of the church, once spiritually “dry” and scattered, now made alive through the Spirit and formed into a unified body under the headship of Christ.
“Bone to its bone,” Ezekiel writes; each part reconnects in precise order. Likewise, in Ephesians 4:16, each believer is a part of a larger structure. The unity of the church is not an accidental or merely human arrangement but a God-ordained knitting together—“through every supporting ligament,” as some translations phrase it. The result is a body “growing and building itself up in love,” an echo of God’s revitalizing power in Ezekiel’s prophecy. For David Jang, the essential lesson is that love, empowered by the Holy Spirit, cements believers in place, guaranteeing that the function of each part harmonizes with the greater whole.
4.3. Love in Action: Practical Expressions of Unity
While “love” can be sentimentalized in popular culture, David Jang emphasizes that biblical love is practical, sacrificial, and deeply relational. Citing 1 Corinthians 13:1–3, he warns that even the most spectacular spiritual gifts—prophecy, knowledge, miracles—are empty if love is absent. Therefore, in the local church:
- Service: Members look for opportunities to serve one another, whether by meeting physical needs, offering support in times of crisis, or bearing one another’s burdens (Gal. 6:2).
- Forgiveness: Conflict is inevitable, but love compels believers to pursue reconciliation (Matt. 18:21–22), reflecting Christ’s gracious forgiveness.
- Encouragement: Hebrews 10:24–25 instructs believers to “stir up one another to love and good works,” assembling regularly and exhorting one another. David Jang underscores this as essential to maintaining a loving community.
- Hospitality and Compassion: Genuine love extends beyond Sunday gatherings, reaching into daily life. Hospitality to strangers, care for widows, orphans, and the marginalized—these are New Testament imperatives (James 1:27; 1 Pet. 4:9).
As these tangible expressions of love abound within the church, internal unity solidifies, external credibility grows, and the church’s witness in society becomes a powerful testimony to the transforming grace of Christ.
5. Discernment Amid Worldly Philosophies and False Teachings
5.1. The Warning of Ephesians 4:14
Ephesians 4:14 admonishes believers not to remain “children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes.” Paul alludes to the turbulence of false teachings, heresies, and worldly philosophies that can infiltrate the church. In the first-century context, these might have included Judaizing teachings, proto-Gnostic ideas, or pagan cultural influences. In the contemporary world, David Jang sees a parallel in the myriad ideologies, self-help philosophies, New Age concepts, and syncretistic spiritualities that saturate the internet, media, and academic discourse.
5.2. Contemporary Challenges: Materialism, Relativism, and Syncretism
Among the dangers Jang enumerates are:
- Materialism and Consumerism: The subtle message that wealth, comfort, and success are the ultimate goals. This can lead to a health-and-wealth “gospel” that equates material prosperity with spiritual blessing, distorting the biblical teaching on stewardship and contentment.
- Moral Relativism: A cultural climate that rejects absolute truth, insisting that all ethical viewpoints are equally valid. This challenges the church’s task of upholding the objective moral directives of Scripture.
- Syncretism: The uncritical blending of biblical faith with Eastern mysticism, secular psychology, or other religious practices. While exploring cultural expressions of faith is not inherently wrong, David Jang cautions that believers must maintain the supremacy of Christ and the authority of Scripture.
- Hyper-Spiritual Sensationalism: Obsessive pursuit of signs, wonders, or mystical experiences without a solid theological foundation. This can result in deception if sensational claims supersede clear biblical truth.
5.3. Guarding Against Deception: The Role of Teaching, Community, and Accountability
How can believers guard themselves and the church against such pervasive influences? David Jang offers several strategies:
- Robust Biblical Instruction: Church leaders should systematically teach Scripture, ensuring that congregations understand the grand narrative of the Bible (creation, fall, redemption, consummation) and the core doctrines of the Christian faith.
- Catechesis and Confessional Statements: Emphasizing historical creeds, such as the Apostles’ Creed and the Nicene Creed, provides believers with a concise summary of orthodox Christian belief. This practice helps anchor congregations in what the church has historically affirmed.
- Critical Thinking and Discernment: Far from discouraging intellectual engagement, Jang urges believers to be thoughtful and discerning, testing all teachings against Scripture (1 John 4:1).
- Prayer and Spiritual Vigilance: Engaging in personal and corporate prayer fosters sensitivity to the Holy Spirit’s guidance and protection. As Jesus taught His disciples, “Watch and pray that you may not enter into temptation” (Matt. 26:41).
- Loving Accountability within Community: When believers are part of a close-knit church family, they can receive correction and admonition if they begin to entertain false doctrines. Isolation is the breeding ground for heresy, while genuine fellowship provides a protective, truth-oriented environment.
David Jang notes that while the church must avoid paranoia or an “us versus them” mentality, it must also heed Scripture’s warnings about spiritual adversaries (1 Pet. 5:8–9) and deceptive philosophies (Col. 2:8). By doing so, the church safeguards its unity and remains effective in proclaiming the gospel to the world.
6. The Church as the Vanguard of God’s Kingdom and the Eschatological Hope
6.1. Moving Beyond Mere Survival to Kingdom Engagement
David Jang frequently describes the church as “the vanguard (전위대) of God’s kingdom.” By this, he means that the church is not a passive entity waiting for Christ’s return but an active participant in the unfolding drama of redemption. While Ephesians 4 focuses largely on internal maturity and unity, its eschatological undercurrent reminds believers of a larger cosmic narrative. Paul repeatedly ties Christ’s exaltation and the church’s mission to God’s ultimate plan to “unite all things in Him, things in heaven and things on earth” (Eph. 1:10).
In practical terms, the “vanguard” mindset calls the church to engage society with the gospel. Unity, growth, love, and discernment are not ends in themselves but tools enabling the church to shine as “salt and light” (Matt. 5:13–16). As members mature, they become more effective witnesses in their homes, workplaces, and communities—demonstrating the reality of the kingdom through their words, deeds, and character. David Jang highlights that Ephesians 4 is not merely a manual for internal church health; it is a summons to embody the presence of Christ in a world longing for hope and meaning.
6.2. The Tension of the “Already and Not Yet”
The concept of the kingdom in Scripture is marked by the tension between the “already” and the “not yet.” Christ has inaugurated His kingdom—He reigns now in the hearts of believers and in the church—yet the full consummation awaits His return. Ephesians 4:13’s phrase, “to the measure of the stature of the fullness of Christ,” points forward to a completion that is yet to come. The church must maintain this forward-looking perspective.
David Jang teaches that acknowledging this tension prevents two opposite errors:
- Triumphalism: Overstating the church’s current achievements and claiming to have fully realized the kingdom, which leads to disappointment when reality does not align with inflated expectations.
- Defeatism: Retreating from the world in despair, ignoring the power of the Holy Spirit to transform lives and communities here and now.
Instead, the church should persevere in mission and holiness, knowing that while perfection awaits the eschaton, significant transformation can—and should—take place in the present age.
6.3. Holiness and Service as Eschatological Witness
A crucial dimension of the church’s eschatological role is living a life of holiness and service. Ephesians 4:22–24 calls believers to “put off your old self” and “put on the new self, created after the likeness of God in true righteousness and holiness.” While this moral exhortation follows in the verses after the key unity passage, David Jang links it intrinsically to the church’s maturity. As the community matures in love, knowledge, and discernment, it must also reflect the character of Christ. In so doing, the church becomes a visible sign of God’s rule breaking into history.
Moreover, the church’s acts of compassion, social justice, reconciliation, and charity bear testimony to the reality of God’s kingdom. For David Jang, these are not mere philanthropic add-ons; they are integral to the church’s identity as the body of Christ. Just as Christ ministered to the poor, healed the sick, and challenged social injustices of His time, so the church must actively engage the world with deeds of mercy and peace. In the words of James 2:17, “Faith by itself, if it does not have works, is dead.” This alignment of spiritual maturity with tangible acts of love underscores the church’s calling to be God’s kingdom outpost on earth.
7. Practical Considerations for Implementing Ephesians 4 in the Local Church
At this point in our extended exploration of David Jang’s interpretation of Ephesians 4, it is helpful to outline concrete steps a local congregation might take to embody these principles:
- Intentional Teaching on Church Unity: Regular preaching series on the nature of the church, rooted in passages like Ephesians 4, 1 Corinthians 12, and John 17. Teach the biblical foundation of unity in the Triune God and the reconciliation achieved by Christ’s blood.
- Gift Discovery and Deployment: Offer seminars or discipleship tracks that help believers identify and develop their spiritual gifts. Encourage diversity in ministry roles—those who serve behind the scenes and those who lead publicly must receive equal honor.
- Cultivating a Balance of Faith and Knowledge: Implement small group Bible studies that delve deep into Scripture and theology while also fostering prayer and fellowship. Regularly emphasize both intellectual growth and experiential trust in God.
- Pathways for Spiritual Growth: Provide clear “on-ramps” for new believers to transition from spiritual milk to solid food. Create discipleship cohorts, mentoring relationships, and leadership training programs that challenge people to press on to maturity.
- Building a Culture of Love: Encourage practical love through service projects, care ministries, and intentional community-building events. Teach conflict resolution and forgiveness as core aspects of discipleship.
- Strengthening Discernment: Address contemporary cultural and philosophical trends from a biblical perspective, equipping members to recognize and refute false doctrines. Remind them of historic creeds, robust biblical theology, and the Holy Spirit’s guidance.
- Engaging the Wider Community: Mobilize the congregation for evangelism, social justice, and missions. Challenge believers to view their vocation, family life, and social networks as spheres of kingdom influence.
- Eschatological Focus: Regularly remind the church that it is part of God’s unfolding story, stretching from Genesis to Revelation. Offer teaching on the “already, not yet” tension, so that believers remain hopeful, patient, and fervent in their calling.
Through these practical measures, the profound truths of Ephesians 4 become more than lofty ideals. They are woven into the daily life and ministry of the church, shaping it into the vibrant, maturing, love-filled body that Paul envisions—and that David Jang passionately advocates.
8. Conclusion: The Comprehensive Message of Ephesians 4 According to David Jang
In reflecting on our extended exploration of Ephesians 4 through the eyes of David Jang, five interlocking themes have emerged, each reinforcing the others:
- Unity and Diversity: The church, rooted in the triune nature of God and bought by Christ’s blood, is fundamentally one. Yet it is also a place of manifold gifts and callings, functioning as a living organism that grows together.
- Faith and Knowledge: Authentic spiritual maturity requires a marriage of trusting faith and deepening knowledge, echoing Paul’s charge in Ephesians 4:13.
- Growth and Maturity: The church must move beyond spiritual infancy, embracing a progressive journey toward Christlike maturity, fueled by solid teaching, prayer, and the Holy Spirit’s work.
- Love as the Core of Unity: Real church growth is “in love” (4:15–16). Truth must be spoken in love; fellowship and service must be guided by love; correction and counsel must be administered in love.
- Discernment against the World’s Winds: Standing firm against the shifting doctrines and values of the age is essential to protect the church’s identity and mission. Faithful teaching, communal accountability, and reliance on the Spirit’s guidance anchor believers in truth.
For David Jang, the upshot of Ephesians 4 is that the church has an urgent, concrete calling to be the forward guard of God’s kingdom. It must not become stagnant or complacent, but continuously aim to “grow up in every way into Him who is the head, into Christ” (4:15). This is not an abstract theological exercise but an intensely practical agenda for every local congregation, every small group, every believer.
8.1. Addressing Real-World Challenges
Ephesians 4 is no stranger to modern challenges. Whether the church faces internal conflicts, doctrinal confusions, spiritual apathy, or external persecution, the principles outlined in this chapter—unity, love, maturity, discernment—provide a biblical pathway forward. David Jang repeatedly reminds believers that the “winds of doctrine” are not a relic of the past; they blow fiercely in the present day, threatening to erode Christian conviction and sow division. Only by clinging to Scripture, cultivating communal love, and relying on the Holy Spirit can the church withstand these tempests.
8.2. A Continuing Journey of Growth
David Jang sums up Ephesians 4 with a simple yet far-reaching statement: “The church is meant to grow.” Growth, however, is not merely about numerical increase—though evangelism is vital—it is about depth, character, and alignment with the life of Christ. Maturity is not achieved overnight; it unfolds through seasons of teaching, testing, repentance, and renewal. This iterative cycle of learning and living out the gospel ensures that the church remains a dynamic force for God’s kingdom.
8.3. The Eschatological Horizon
Finally, Ephesians 4 does not culminate in a static blueprint for “the perfect church.” Rather, it drives us toward an eschatological vision: one day, the church will indeed reach “the measure of the stature of the fullness of Christ” (4:13). In that day, the partial knowledge we now possess will give way to the fullness of divine revelation (1 Cor. 13:12). Yet until then, the church stands under Christ’s lordship in the here and now, pressing on in hope, bearing witness to the world through its unity, holiness, and love.
David Jang encourages believers to maintain a vigilant longing for Christ’s return and the consummation of God’s kingdom. Simultaneously, he urges them to invest wholeheartedly in the present mission, where growth and maturity are forged in the crucible of everyday life. This tension—a future hope fueling present faithfulness—animates the entire chapter of Ephesians 4.
Closing Exhortation: Living Out Ephesians 4 Today
The call of Ephesians 4, as David Jang interprets it, invites every Christian and every church community into a profound journey of transformation. It beckons us to experience:
- A unity that transcends human barriers, grounded in the triune God.
- A diversity of gifts that honors each member and enriches the ministry of the whole.
- A fusion of faith and knowledge that guards against both empty emotionalism and dry intellectualism.
- An ever-deepening growth in spiritual maturity, culminating in Christlikeness.
- A love that binds all aspects of church life, making the body robust and resilient.
- A discernment that resists the siren calls of contemporary culture, preserving the church’s purity and witness.
- An eschatological vision that propels believers to serve faithfully now, anticipating the day when Christ’s kingdom is fully revealed.
In a world grappling with uncertainty, division, and competing ideologies, the model of a unified, growing, loving, and discerning church is desperately needed. Ephesians 4 holds out an inspiring blueprint—and David Jang’s expositions push us to apply that blueprint in tangible ways, for the glory of God and the blessing of the nations. Indeed, when the church embraces its vocation to “grow up in every way into Him,” it stands as a radiant beacon of hope, embodying and proclaiming the life-transforming gospel of Jesus Christ.
“The church is meant to grow.”
— David Jang
May that defining conviction echo in our hearts and guide our ministry efforts. If the church truly heeds the message of Ephesians 4, then it will not only protect itself from deceptive winds of doctrine but also become, in its love and maturity, the very fragrance of Christ in a broken world. And in that faithful witness, the ultimate reality of God’s kingdom—the grand consummation that Paul glimpses in Ephesians—will draw ever nearer, as God’s people become a living testimony of redemption until the day they stand face to face with the Savior Himself.
