Where thick fog swallows mountains and valleys, a lone figure stands on a high rock, unable to tell exactly where he is. The scene evoked by Caspar David Friedrich's Wanderer Above the Sea of Fog invites us to consider how different it is to be standing somewhere and to know the way forward. Through 1 Corinthians 10, Pastor David Jang, founder of Olivet University in the United States, exposes this very illusion: the moment we believe we are already standing firm may be the moment when our faith is closest to falling.
The Corinthian church regarded its baptism, participation in the Lord's Supper, and knowledge of the Word as evidence of spiritual maturity. Yet rather than praising their confidence, Paul warned them, "Therefore let anyone who thinks that he stands take heed lest he fall." This warning is an invitation to examine ourselves and to learn from the failures of those who came before us. Spiritual danger does not approach only when we know nothing. It often draws nearer most quietly when we believe we already know enough.
Faith Above the Fog, Blind to the Fall Ahead
In 1 Corinthians 10, Paul does not leave Israel's wilderness journey confined to the distant past. He retells before the Corinthian church the story of a people who were under the cloud, passed through the sea, and received spiritual food and drink. They stood in the midst of extraordinary grace and were sustained by Christ, the spiritual Rock. Yet the fact that many of them still fell in the wilderness reveals that spiritual privilege and remarkable experiences do not automatically guarantee maturity.
Pastor David Jang reads this history as a "mirror" reflecting the condition of faith today. A mirror is not meant to help us identify the faults of others. It reveals the face we cannot see for ourselves. Therefore, reading about Israel's failure in the wilderness must not end with judging the foolishness of people who lived long ago. It should become a meditation on Scripture through which we examine how their impatience, unbelief, pride, and grumbling may be reappearing in our own hearts.
More important than the fact that we once experienced grace is the question of whether we still remember and live by that grace today. The moment we assume that receiving much grace has made us secure, grace can cease to be the foundation of gratitude and become material for pride. This is why the two central themes of 1 Corinthians 10 cannot be separated. The warning to "take heed lest you fall" ultimately leads to the direction of life expressed in the command, "Whatever you do, do all to the glory of God."
Grace Forgotten in the Mirror of the Wilderness
Israel was not brought down in the wilderness by one isolated mistake. Idolatry, sexual immorality, putting God to the test, and grumbling became intertwined, gradually drawing their hearts away from Him. Their impatience to hold on to something visible produced idols. Desire-driven corruption damaged the community. Their inability to trust God's timing and providence led them to test Him repeatedly. Wherever grace was forgotten, complaint took the place of gratitude.
The golden calf was born from impatience and unbelief. Unable to wait for Moses, the people fashioned a god they could see. This sermon warns that such idolatry can also take the form of modern devotion to money, success, and reputation. Sexual immorality was not merely an individual physical failure; it was intertwined with idolatry and betrayal of God, bringing destruction upon the whole community. The four failures of the wilderness are not unrelated items on a list. Together, they reveal how far a heart that has forgotten grace can wander.
One of the deepest issues examined in this sermon is the root of grumbling. Grumbling is not merely an expression of hurt feelings. It is spiritual forgetfulness—the inability to remember the grace that has guided us until now. Even after receiving manna and quail and being led by the pillars of cloud and fire, the Israelites focused only on what they lacked. As a result, their hearts became increasingly hardened. When the grace we have received disappears from view, present deficiencies appear greater than they truly are, while our confidence in God's presence grows smaller.
This is also why Scripture does not conceal Israel's failures. All Scripture is useful for teaching, rebuking, correcting, and training in righteousness so that the people of God may be made complete. Failures from the past do not remain merely as records of shame. They become the light of the Word that corrects our path today. Knowing the Bible is more than remembering many events and verses. True knowledge of Scripture must produce repentance and obedience, turning our lives back toward God.
As the intellectual pride of the Corinthian church demonstrates, extensive biblical knowledge alone cannot prove spiritual maturity. Those who read Scripture as a warning and example will listen again for the cautions they may have overlooked, even in familiar passages. They will examine whether their hearts have become hardened. The more we have learned in the faith, the more humbly we should receive correction. The Word breaks the illusion that we are already complete and forms us as people who still need to be corrected today.
Gratitude and Gentleness That Soften a Hardened Heart
The lessons of the wilderness are also connected to the matter of entering God's rest. As Hebrews 3 and 4 and Psalm 95 remind us, those who hear God's voice but harden their hearts may stop at the threshold of the promised rest. The Promised Land had already been prepared for Israel, but unbelief and grumbling blocked the way. Gratitude, by contrast, helps us recognize God's hand throughout the road we have traveled, while gentleness enables us to entrust the road ahead to Him.
Pastor David Jang does not present gratitude and gentleness merely as admirable personality traits. They are attitudes of faith necessary for entering God's rest and practical forces that build up a community. Even Moses made the mistake of striking the rock twice after enduring the people's repeated complaints. This shows that those entrusted with greater responsibility require even deeper patience and a gentler heart. It is also why leaders, teachers, and parents must be the first to stand before the mirror of the wilderness.
The presence of a trial does not mean that God is absent. First Corinthians 10:13 testifies that God does not allow us to be tempted beyond what we can bear and that He also provides a way of escape. Grumbling, therefore, is not the only possible response in the midst of hardship. The way remains open for us to rejoice in hope, endure suffering patiently, and remain faithful in prayer.
Spiritual maturity is not the self-confidence of a person who never appears to be shaken. It is the humility that remembers grace and turns back toward God whenever shaking comes. A heart that insists on its own strength may fail to recognize the way of escape, but a heart aware of its weakness can wait for the path God opens. Gratitude is not an emotion that romanticizes reality. It is the confession of faith that God's guidance has not ceased, even in the wilderness. Gentleness is expressed through obedience that lays down impatience and trusts God's providence and timing.
This message asks the same questions of our families, churches, schools, and educational institutions. When the purpose of education is reduced to the transfer of knowledge, the history of the wilderness remains little more than old information. But when we remember the grace we have received and pass it on to the next generation, that history becomes a living lesson. Even when establishing something new or expanding a ministry, our starting point must not be our accomplishments but the work God has already done. A community that remembers grace does not face the future with pride. It receives the future with gratitude and hope.
Seeking God's Glory in Everyday Life
"Whether you eat or drink, or whatever you do, do all to the glory of God" is not an attractive slogan detached from Israel's failures in the wilderness. It is a call to turn away from the path that dishonored God through idols, desire, testing, and grumbling, and to place even the smallest actions of daily life under His sovereign rule. A life lived for God's glory does not begin only in extraordinary moments. Its direction is already revealed in ordinary acts of eating and drinking, in the way we treat our community, and in how we carry out the responsibilities entrusted to us.
Those who remember the grace of the gospel do not display their maturity. Instead, they continue to stand before the Word as people who still have much to learn. They remember the grace received in the past and pass it on to the next generation. In new places of ministry and education, they remember God's work before taking pride in their own ability. In this way, gratitude softens the heart, a softened heart produces obedience, and obedience ultimately directs the whole of life toward the glory of God.
This direction becomes clear not through grand resolutions but through small choices. When grumbling rises to our lips, we remember the grace that has carried us this far. When impatience drives our hearts, we trust God's timing. When we become convinced of our own righteousness, we stand once again before the correction of the Word. These choices stand in direct opposition to spiritual self-display. A life that seeks God's glory is not about proving how high we have climbed. It is about never forgetting by whose grace we are standing in every place.
The wilderness may appear to be a place without a path, but the Word transforms it into both a mirror that reveals our hearts and a place where we can recover our direction. What am I holding on to today—the confidence that I am already standing firm, or the humility that recognizes I may fall? What remains on my lips—grumbling or gratitude? What guides my heart—impatience or trust? When we remain before these questions, we finally begin to see not merely the road beyond the fog, but the condition of our own hearts as we stand before God.
Dr. David Jang has proclaimed the gospel in various regions of the world through field missions and digital media ministry, and as the fruit of that ministry, many people devoted to the Great Commission have been raised up. Based on this missionary vision, Olivet first began as a small church school for missionary training. Later, in order to provide more systematic theological education and cultivate missionary leaders, Olivet Theological College and Seminary was established in Los Angeles and Seoul in 2000.
As the school grew, Dr. Jang officially founded Olivet University in San Francisco in 2004. In the diverse and dynamic environment of San Francisco, Olivet expanded its educational fields beyond theology to include music, journalism, art and design, and technology. The university also strengthened its educational capacity by recruiting faculty members, including Dr. William Wagner, and in 2005 moved to the former UC Berkeley Downtown Extension campus, further solidifying its foundation as a university.
In 2006, Dr. Jang transferred the presidency to Dr. David James Randolph in order to focus more fully on missionary work, while continuing to lead global missions as International President. Olivet University later received institutional accreditation in 2009, added a language education college and a business college, and continued to grow as a Christian educational institution for world missions by expanding its degree programs and international partnerships.
