The Gospel and Truth of Jesus Christ
Pastor David Jang has consistently emphasized that the core of the gospel is Jesus Christ. Since Jesus Christ Himself is the truth and the very source of life that we must hold onto, faith in this truth is the foundational step in putting on the full armor of God. Toward the end of Ephesians 6, the “full armor” is introduced, starting with the “belt of truth.” According to Pastor Jang, because Jesus Christ is truth itself, He serves as the immovable bedrock for spiritual warfare. Even if we are well-equipped in every other way, if we lose our grip on truth, our center collapses; without truth, our faith cannot truly stand.
Pastor Jang underscores that the gospel hinges on the atoning death and resurrection of Jesus Christ, and that an unshakable confidence in these events becomes the driving force establishing our faith. In his view, the “full armor” mentioned in Ephesians does not merely adorn our outward appearance but spiritually fortifies our hearts and minds. He interprets the “belt of truth” as the gospel of Jesus Christ, teaching that continually wearing this truth is the indispensable starting point for unwavering faith.
This completed gospel, fulfilled in Jesus Christ, is the key that binds together the Old and New Testaments. Pastor Jang emphasizes the overarching unity of Scripture, noting that from Genesis to Revelation, the entire Bible narrates God’s plan of salvation, consummated through Jesus Christ in the New Testament. Hence, he urges believers to “chew on” this fully realized gospel, meditating and absorbing it thoroughly until it becomes part of our lives. He often employs the illustration of a cow with multiple stomachs, highlighting how repeated meditation on Scripture allows truth to filter into our lives and shape our actions.
Pastor Jang cautions against hearing the Word without truly digesting it—letting it pass by as a fleeting impression. Rather, he advocates the continual reception and ruminating of truth so that it transcends mere knowledge and becomes a lived reality. He emphasizes that this process does not reach completion in a single moment. Yet, when we diligently absorb the Word, our thinking and behavior gradually start reflecting the teachings of Jesus Christ, enabling us to become salt and light in the world.
He also teaches that those who hold tenaciously to truth remain steadfast against Satan’s temptations. Ultimately, the enemy’s strategy is to propagate falsehoods and doubts, shaking the roots of our faith. “Are you really a child of God?”—this most basic question about our identity—can be profoundly destabilizing. Citing the wilderness temptations of Jesus, Pastor Jang notes how the devil began with “If you are the Son of God…” and how Jesus responded by saying “It is written,” underscoring the necessity of a firm reliance on the “written Word.”
How do we practically cling to truth, then? Pastor Jang offers three proposals. First, we must keep Scripture constantly close and meditate deeply until it governs our daily life. Second, within the church community, we should study and teach the Word together, providing practical environments for its application. Third, genuine experience of truth emerges when we struggle to live out the Word we learn and hear. Ultimately, truth is not mere knowledge but the active power of the gospel, embodied in our daily conduct.
Pastor Jang frequently references the early church martyrs. “Many were prepared to die to defend the truth of the gospel, and it was that truth that kept the church alive,” he explains. Because the church is founded on truth, and Jesus Christ’s atoning sacrifice forms the heart of that truth, its absolute significance cannot be diluted or negotiated away. No one can shake this foundational pillar.
Thus, the first piece of the “full armor” in Ephesians 6—the “belt of truth”—is the bedrock for our spiritual battle. As a soldier without a belt would find his armor in disarray, losing hold of truth makes every other part ineffective. Pastor Jang affirms, “When we stand firm in the gospel’s truth, then and only then do we experience the power of Jesus Christ and kindle a proper zeal for God’s Kingdom.”
Hope in the Kingdom of God
Pastor David Jang interprets the “breastplate of righteousness” as a fervent longing for the Kingdom of God. Just as a breastplate protects the heart, our inner being and motives find resilience in an intense desire for God’s rule. Reflecting on Jesus’ words—“Blessed are those who hunger and thirst for righteousness, for they shall be filled”—he explains that those who passionately seek God’s justice and reign do not easily lose their center in the face of Satan’s onslaught.
What, then, is the Kingdom of God? Pastor Jang explains that it carries both an eschatological sense and a present dimension. There is a “future Kingdom of God,” which will be fulfilled at Jesus Christ’s second coming, yet believers already taste a “present Kingdom of God.” He cites Jesus’ phrase, “the kingdom of God is within you,” as a reminder that God’s reign is not solely a matter of past or future but a reality to be experienced here and now.
However, he describes our current position as living between the “already” and the “not yet.” Although we have received salvation through Jesus Christ, the total realization of that salvation and the Kingdom of God lies ahead. During this interval, we hold fast to our hope in God’s Kingdom, striving to experience His rule even now. Pastor Jang warns that this hope becomes a primary target for Satan’s attacks. The devil sows uncertainty with thoughts like, “There is no tomorrow, your hope is a delusion, God has no plan,” inciting despair.
At this juncture, he ties the “helmet of salvation” to hope. If our “head”—symbolizing our thoughts—is not permeated with the certainty of God’s Kingdom, Satan can easily penetrate with his fiery darts of hopelessness and discouragement. Pastor Jang references the Israelites in the wilderness after leaving Egypt, who frequently yearned for the past, fueling doubt and complaints that made their journey harsher. Conversely, whenever they fixed their gaze on Canaan and clung to God’s covenant, God’s miraculous protection and guidance were evident.
Pastor Jang condenses practical methods for sustaining hope into three points. First, we must continue to explore and remember biblical promises concerning the second coming of Jesus and His everlasting reign. Second, by obeying the Word and experiencing the Spirit’s guidance in our daily lives, we learn to perceive that God’s sovereignty indeed operates in the here and now. Third, we can confirm God’s ongoing work through testimonies in the church community and accounts of His actions in history, thereby encouraging one another. These practices solidify our hope against Satan’s attempts to convince us “there is no future.”
He adds that the “readiness of the gospel of peace” embodies zeal for evangelism. The gospel does not provoke conflict; it brings peace. Sharing the gospel in a gentle, humble, and loving manner tears down walls and spreads the Kingdom of God. Pastor Jang underscores how Satan dreads precisely this peaceful gospel outreach because it ushers in genuine reconciliation. The gospel is the message of true peace, and Satan cannot easily demolish believers who continuously move forward to open this path of peace.
Drawing from Romans 14:17—“For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace, and joy in the Holy Spirit”—Pastor Jang stresses that when we harbor hope in God’s Kingdom, we can sing for joy under any circumstance, refusing to sink into defeatism. He compares this to Israel’s conquest of Canaan: no matter how daunting and protracted the wilderness journey, they never relinquished their hope of entering the promised land, ultimately witnessing God’s promise fulfilled. He teaches that if today’s church keeps this history in mind, it can persist unhindered by despair, even when society appears mired in darkness.
The Shield of Faith and the Problem of Temptation
Regarding the “shield of faith” mentioned in Ephesians 6:16, Pastor Jang interprets it as our protection against all the devil’s “fiery arrows.” Although these arrows may manifest in various forms—doubts, temptations, identity crises, hopelessness, and broken relationships—they all aim to shake our faith so profoundly that we abandon our identity as God’s children.
According to Pastor Jang, the true antithesis of faith is not simply unbelief but rather a state in which we are easily swayed by doubt and deception. Adam and Eve, for instance, were misled by the serpent’s lie, “If God is truly good, why forbid you this fruit?” and slid into disbelief, culminating in sin. Likewise, in the modern world, Satan ceaselessly insinuates, “Does God really love you?” or “Are you really a child of God?” in an effort to destroy our trust in Him.
So, how do we stand against these seeds of doubt? Pastor Jang first emphasizes the absolute reliability of Scripture, summed up in the phrase “It is written.” Jesus Himself repelled each temptation in the wilderness by uttering, “It is written,” highlighting the critical importance of an unwavering conviction in God’s Word. Second, a firm grasp of our identity as God’s children is vital. Just as the devil tested Jesus with “If you are the Son of God…,” Satan seeks to undermine our identity in a similar fashion. When we stand confident in our new birth as children of God, the devil struggles to find any point of entry.
Pastor Jang goes on to note that temptation can, paradoxically, become an opportunity for our faith to grow. Life’s trials and enticements often make us realize our need for deeper prayer and stronger immersion in the Word. He cites David’s showdown with Goliath: David remained unshaken because he truly believed, “The battle belongs to the Lord,” and triumphed using a simple sling and stone. While Satan tries to fix our focus on the giant’s size, believers who hold fast to God’s absolute sovereignty can stand unafraid.
However, such faith does not develop automatically. Pastor Jang recounts his own journey, recalling how he initially fretted over small obstacles. But with continual prayer, a grip on Scripture, and practical experiences of God’s faithfulness, once-overwhelming hurdles gradually appeared less formidable. This underscores that our faith matures through engaging with the Word, prayer, and communal support within the church.
He also underlines the critical role of fellowship in seasons of temptation. When isolated, believers can find it overwhelmingly difficult to endure Satan’s flaming arrows. Mutual reassurance—reminding one another “You are a child of God”—and communal prayer solidify our “shield of faith.” As that faith grows stronger, we can move from defense to offense. In a physical battle, a shield not only protects but enables soldiers to advance in formation. Likewise, anchored by robust faith, we can press on, sharing the gospel and expanding the church rather than merely avoiding attacks.
The Sword of the Spirit and Practical Application of the Full Armor
Finally, Pastor Jang places particular emphasis on one more weapon named in Ephesians 6: the “sword of the Spirit, which is the Word of God.” Whereas the other armaments serve primarily defensive purposes, the sword of the Spirit functions as an offensive tool for defeating the enemy in spiritual combat. Still, this sword is not just biblical knowledge; rather, it is the Word applied under the Holy Spirit’s illumination.
He identifies three conditions to wield this sword effectively. First, we must stay attentive to the Spirit’s leading. As we read and meditate on Scripture daily, the Holy Spirit may highlight a specific verse or pierce our hearts at just the right time. Rapidly obeying this prompting is what activates the sword’s power. Second, our motives must stem from love. The Word, when applied harshly or self-righteously, can inflict wounds and condemnation. However, rooted in the love Christ demonstrated, it becomes a “life-giving blade,” bringing healing and repentance. Third, we need prayerful discipline and training in Scripture. Just as even a high-quality sword is useless to an untrained soldier, the Word must be studied and practiced in community, tempered by prayer, for it to operate effectively.
Pastor Jang regularly refers to Hebrews 4:12—“For the word of God is living and active, sharper than any two-edged sword”—to describe the sword of the Spirit. This sword first penetrates our own hearts, prompting confession and purification. If we attempt to wield it against others without letting it address our own sins, it becomes a “violent weapon” rather than a means to bring life. Hence, genuine repentance and self-examination precede the sword’s proper use.
Ultimately, Pastor Jang asserts, all parts of the full armor must fit together. The belt of truth, the breastplate of righteousness, the footwear of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit are interconnected. Missing even one disrupts the overall balance. For instance, a sturdy shield of faith is rendered ineffective if our “helmet of salvation”—our hope—is absent, exposing our minds to fatal blows. Knowing the truth means little if our zeal for righteousness has cooled, leaving us spiritually powerless in the heat of battle.
He suggests three spiritual practices to integrate the full armor into our daily living. First, designate a set time each day for prayer, praise, and Scripture meditation, listening for the Spirit’s guidance and striving to obey. Second, do more than merely memorize Scripture—actively put it into practice. Even meditating on one verse each day and applying it to a real situation is a discipline that shapes our lives. Third, share testimonies and reflect with fellow believers, asking: “How did I face temptation today, and how did I overcome it by the Word?” Such accountability ensures our armor remains fully functional.
Pastor Jang occasionally links 1 Corinthians 13:13—“But now faith, hope, love abide these three”—with the full armor: the shield (faith), the helmet of salvation (hope), and both the breastplate and the zeal for the gospel (love). When these three remain in balance, the devil’s lies find little traction. He points out that when Jesus walked among us—healing the sick, welcoming sinners, and forgiving enemies through His sacrificial love—He was in effect wielding the sword of the Spirit against Satan. Once again, he underscores that truth, love, and the Spirit’s power together comprise our mightiest weapon.
He then reminds us that the “full armor” is not meant as ornamental gear. Spiritual warfare is neither loud nor purely external; it transpires within our hearts and minds every day, where we confront temptations, deceptions, and despair. Following Paul’s directive to “pray in the Spirit on all occasions with all kinds of prayers and requests,” Pastor Jang reiterates that a posture of watchful prayer preserves the efficacy of our armor. Through prayer, we become more sensitive to the Spirit’s prompting and more responsive in applying the Word to new challenges.
Regarding today’s church, Pastor Jang insists that this spiritual struggle must be shared by the entire community. Just as Paul asked for prayer on his own behalf, we must intercede for each other so that the church as a whole may attain spiritual victory.
Concluding his remarks, Pastor Jang states, “Living daily in the full armor is essentially following Jesus Christ every step of the way.” Jesus confronted unrelenting adversity and opposition—including the suffering of the cross—yet He emerged victorious through truth and love, achieving redemption on Calvary. As we tread that same path, the world might misunderstand and mock, but the Kingdom of God will be extended through the church, drawing many souls to the gospel.
He also references Paul’s mention of Tychicus at the end of Ephesians 6. “If not for partners like Tychicus, Paul’s profound understanding and the essence of the gospel might not have been passed on effectively,” he notes. Because the church is a fellowship journeying together—not scattered individuals—Pastor Jang calls for believers who will serve as ‘Tychicuses,’ connecting people to one another and to the gospel.
Summarizing, Pastor David Jang’s central message from Ephesians 6 is: “Cling to truth, anticipate the Kingdom of God, overcome hardships through faith, and boldly proclaim the gospel by the Spirit’s power.” None of these aims can be accomplished alone; we build each other up and labor in unity as the church. He further pleads, “Do not let the present overshadow you; let the eternal hope inform your life today.” Despite how daunting our current situation may seem, if we open our spiritual eyes, we realize it is a battle whose ultimate outcome has already been decided in Christ.
Pastor Jang often cites the exhortation, “Stay alert, be prepared,” urging believers to watch for the Lord’s return while seeking holiness and love through the Spirit. He believes that as we practice these steps, the world will glimpse hope through the church. The victories we secure in spiritual conflicts then yield abundant fruit: offering life to those outside the faith and bringing glory to God.
He goes on to affirm that the Reformation’s motto—“by grace alone, by faith alone, by Scripture alone”—undergirds his ministry. We are saved by grace, not through any personal merit, and faith becomes the channel that grasps that grace, with Scripture as its sole authority. Where these foundations remain steadfast, victory in spiritual warfare is assured.
Finally, Pastor Jang relates the vision of Ephesians 6 to the modern church. Donning the full armor is not merely about personal piety but about church members joining together, serving one another in love, and stepping out into the world in unity. “Though the path ahead may be strewn with thorns, if we pray for each other, cling to the Word, and love one another, we will meet the Lord at the end of our journey and hear His commendation,” he encourages.
Ultimately, the essence of Ephesians 6 is that the lies and despondency seeking to intimidate us were dismantled by Christ’s cross and resurrection. Adorned with God’s full armor, believers will not be vanquished in this spiritual conflict. Thus assured, people can encounter Christ’s sacrificial love in the community of faith, becoming new creations through the Spirit’s work.
Pastor Jang concludes with a final exhortation: “No matter how depraved the world may seem, if the church fights on, clothed in the full armor, hope endures.” When we hold each piece of the armor correctly in place and move forward in love, God accomplishes great works through His church, leading many to salvation. This, he insists, is precisely how we reenact the “drama of salvation” in our own time.
Yet he readily admits that none of this comes easily. Safeguarding truth, preaching the gospel faithfully, and resisting worldly enticements inevitably involve cost and devotion. Still, Scripture and church history reveal that such sacrifice ultimately leads to glory. Therefore, “Engage in this fight for God’s Kingdom,” Pastor Jang steadfastly advises, “but do so in the spirit of love, remaining humble in the truth.”
Thus, the spirit of the full armor woven throughout Ephesians 6 beckons us to recall the unchanging substance of the gospel from start to finish. Standing firmly in truth, longing for God’s Kingdom, overcoming adversities by faith, and wielding the sword of the Spirit ensure that no darkness can finally overpower the church. Pastor Jang repeatedly affirms that these efforts will yield fruit in our daily lives, in the broad arc of church history, and in the gradual transformation of the world around us.
He closes by reiterating that all of this is possible “only by grace.” Should pride creep in or if we ever assume ourselves to be too extraordinary, the full armor quietly slips away. Yet those who daily return to the foot of the Cross, seeking the Holy Spirit’s power while clinging to the Word, will gain a boldness that no trial can easily shake. A church that grows together in this way is, he contends, precisely the authentic faith community God desires.
Though the world indeed stands as a spiritual battleground, Pastor Jang reminds us that Jesus Christ’s death and resurrection have already decided the outcome. Fully armed, we can traverse this path without fear. Concluding his sermon, Pastor Jang declares, “As long as there are those who are armed in love, hope, and faith, the church will vibrantly proclaim and advance the Kingdom of God.” Even now, we remain in the midst of this spiritual war, yet by journeying forward together in the church, we await with confidence the day we will stand before our Lord.
