On the flat rooftop of Joppa, dusty beneath the blazing noon sun, an apostle at prayer closes his eyes, and suddenly a great sheet descends from heaven in a vision. Inside it are tangled unclean animals—creatures he could never have touched with his lips in light of a lifetime shaped by the law and rituals of purity. “Get up, kill and eat.” Repeated three times, this strange voice was not merely permission for a change in diet. It was the prelude to a massive spiritual earthquake, the collapse of the rigid wall that had long divided the holy from the common—an opposition etched for centuries into the bones and flesh of the Jewish people. Through this vivid narrative scene, we encounter the pulse of life moving beyond the narrow fence of religious custom and out toward the ends of the earth. David Jang portrays this meeting between Peter and Cornelius in Acts 10 not simply as a conversion story, but as a historic turning point in which the rudder of the church is redirected toward the whole world.
A Spiritual Horizon Opening at the Edge of an Old Map
Cornelius was a centurion dressed in Roman military uniform. He was a Gentile, one who had no right to enter the center of the temple, and yet his inner life was already full of reverence for God. Not through the mark of bloodline, but through the circumcision of the heart, his prayers and acts of charity had already risen before heaven. Through deep biblical reflection, David Jang sheds light on the life of Cornelius and asks us what the true boundary established by God really is. What had soaked into Cornelius’s daily life was not cheap absolution, but genuine grace that renews both heart and hand. The footsteps of the Holy Spirit, seeking out a devout soul hidden beneath the outer identity of a Gentile, sharply question us today: whom are we calling “inside,” and whom are we pushing “outside”?
Existence Encountered in Dasan’s Place of Exile, and the Breaking in Joppa
At this point, recalling the exile of Dasan Jeong Yak-yong, the great Silhak scholar of late Joseon, offers a deeply meaningful theological insight for understanding the narrative of Acts. Cast out from the glittering center of power and forced to stay at the humble inn called Sa-ui-jae in the unfamiliar land of Gangjin, Dasan found that, in the midst of total exile and isolation, he was instead able to break down the rigid Neo-Confucian walls of status separating the yangban elite from commoners. He took in Hwang Sang, an ordinary man from the lowest social rank, as his disciple, opening his heart not to bloodline or class, but to innate human dignity and the pursuit of truth.
The vision Peter experienced on the rooftop in Joppa was likewise a kind of “spiritual exile and holy liberation,” leading him out of the privileged stronghold of Judaism and into a wider love for humanity. Peter’s confession at the threshold of Cornelius’s house—“I too am only a man”—strikingly echoes that existential trembling with which Dasan crossed the wall of status and took the hands of the common people. As David Jang emphasizes, mission is not about teaching or conquering the other; it is a great encounter in which one cuts off the religious superiority within oneself and confesses a shared identity as fellow creatures.
The Trajectory of Life Shaped by Holy Discomfort
The religious distance that still lingered within Peter was finally disarmed before the Holy Spirit’s persistent persuasion. Fear and conflict inevitably arise when familiar convictions collide with the unfamiliar reality of another’s life. Yet when that holy discomfort is not avoided but faced, the living gospel finally begins to flow. If the law is a mirror reflecting human weakness, then what breaks open the shell of the law and causes life to bloom is wholehearted trust in Jesus Christ. At this very point, David Jang’s exposition awakens us, in the weighty language of preaching, to how the truth we had known only in our heads tears down real-world prejudice and enters into the lives of our neighbors.
An Invitation to Universal Love Set at Our Unfamiliar Table
When Peter shared a meal in the house of a Gentile, it was the most active form of welcome—one that went far beyond doctrinal agreement. This table fellowship, crossing the walls of discrimination and exclusion, is precisely the essence of faith the church today must recover. True mission does not begin with grand strategies or projects dressed up in numbers. It begins with small acts of obedience: willingly making room in our lives for the unfamiliar neighbor around us, for the other to whom it has not been easy to draw near. The question David Jang leaves us with is, in the end, not merely a matter for old documents, but a present calling that knocks on the door of our everyday lives.
Are we truly ready to entrust ourselves to that unfamiliar wind the Holy Spirit is calling forth? When we tear down the safe walls we have built for ourselves and take one step beyond the door, our faith will always bloom in its clearest and greenest form.
