The 20 Greatest Revivals in History: When Jesus’s Promise in John 14:12 Came to Life

The 20 Greatest Revivals in History: When Jesus’s Promise in John 14:12 Came to Life

Promessa de Jesus - avivamentos cristaos

A Promise That Keeps Being Fulfilled

Just before He was arrested, on His last night with the disciples, Jesus made a promise we sometimes forget to take seriously. He said that the one who believes in Him will also do the works He did, and even greater works. In the words of the King James Version: “Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father” (John 14:12).

That promise did not die in the first century. It has run through church history like a river that, from time to time, overflows its banks: multitudes seized by conviction, cities transformed within a few weeks, countries where the gospel seemed impossible to take root suddenly seeing churches spring up by the thousands.

Over the last three centuries this overflow has happened again and again, and it has left a trail. Secular newspapers, often skeptical ones, sent reporters to cover services that lasted for weeks. Governments recorded church growth in official censuses. Historians at universities such as Yale, Cambridge, and Oxford have devoted entire careers to studying these events, because their scale and social impact were too great to ignore.

This article gathers twenty of those episodes. I write as a pastor, and as someone who has spent years reading theology and church history. I am not Catholic; I am evangelical, and I don’t hide that. I also won’t force adjectives onto the story — the facts are strong enough on their own. Each account here rests on primary, journalistic, and academic sources. The idea is for the reader to see, calmly, that faith and historical evidence can walk together. We begin with a Protestant village nearly torn apart by internal quarrels, in the Germany of 1727, which would become the birthplace of the longest unbroken prayer movement in modern church history.

Herrnhut (1727): A Village on the Verge of Falling Apart

In 1722, Count Nikolaus Ludwig von Zinzendorf opened his estate in Saxony to Protestant refugees fleeing Catholic persecution in Habsburg territory. Five years later, the community was split by doctrinal disputes among Lutherans, Calvinists, Moravians, and Waldensians. Zinzendorf began visiting families one by one, seeking reconciliation.

On August 13, 1727, during a communion service, everything changed. A wave of conviction and repentance swept over the congregation with such intensity that tradition came to call that day the “Moravian Pentecost.” Out of it grew one of the most remarkable prayer movements ever recorded: a round-the-clock schedule of intercession, in shifts, that continued for more than a hundred consecutive years, according to the Moravian Church’s own records.

Zinzendorf documented the episode in diaries now preserved in Moravian archives in Herrnhut and in Bethlehem, Pennsylvania. Within a few decades, that once-fractured village became one of the most effective missionary forces in Protestant history, sending workers to the Caribbean, Greenland, and Africa in a proportion far beyond what any community of its size had attempted before. Years later, John Wesley would cross paths with Moravians during a storm at sea, and at a meeting on Aldersgate Street in London he would feel his heart “strangely warmed.” He himself attributed that turning point to the steady faith of the Moravians, and the scene became a founding moment for worldwide Methodism.

Herrnhut illustrates something we will see again in this list: a single gathering of genuine prayer can set off waves of faith that cross centuries and continents.

The First Great Awakening (1730–1743)

Benjamin Franklin — printer, skeptic, and no candidate for conversion — went to hear George Whitefield preach outdoors in Philadelphia. Curious about how far that unamplified voice could really carry, he began walking backward through the crowd until he could no longer make out the words. Doing the geometry himself, he concluded, in his own autobiography, that Whitefield could be heard by tens of thousands of people at once. It’s a technical data point from a nonbeliever, and it confirms what the religious accounts were already saying: that awakening had continental scale.

Between 1739 and 1741, Whitefield crossed the American colonies preaching in town squares and marketplaces, drawing crowds disproportionate to the size of colonial towns. New England churches recorded spikes in new membership. Jonathan Edwards documented the phenomenon with theological rigor, describing whole communities gripped by a deep sense of repentance and living faith.

Historian Thomas S. Kidd, of Baylor University, has written extensively on how this awakening united the colonies across denominational lines, in a spiritual movement that would shape the religious character of the United States for centuries.

Northampton and Jonathan Edwards (1734–1735)

Northampton, Massachusetts, was not an obvious place for a revival: a prosperous, Puritan town, pastored by one of the most rigorous and cerebral theologians of the Reformed tradition, Jonathan Edwards, a man of long sermons and relentless argument.

At the end of 1734, two young people in the town died suddenly, and the shock shook the community. In the months that followed, something unprecedented happened there: virtually the entire town, just over two hundred families, was gripped by an intense sense of spiritual conviction. Hundreds of genuine conversions in a few months, in a tiny town.

What makes this episode singular is the quality of the primary source. Edwards was no effusive evangelist. He was a meticulous observer, and he wrote A Faithful Narrative of the Surprising Work of God (1737), documenting God’s work in that community case by case. The book was read in England and cited directly by Wesley and Whitefield as an inspiration for their own ministries.

The original manuscript is preserved today at Yale’s Beinecke Rare Book & Manuscript Library. It is one of the most closely studied primary sources in American religious history — proof that this awakening was not the exaggeration of an era, but an event documented with the same care historians would give any other landmark.

Cane Ridge (1801): Twenty Thousand People on the Kentucky Frontier

Kentucky, at the turn of the nineteenth century. A violent frontier, isolated families, almost no formal church structure. In August 1801 Presbyterian minister Barton W. Stone organized a camp meeting meant to last just a few days. Witnesses estimated the crowd at up to 20,000 people, a staggering number for a sparsely populated region. Historian Paul Conkin used the logistics required — the sheer quantity of wagons, horses, and provisions — to corroborate those estimates. Gathering that many people there took an effort comparable to moving a small army, and yet it happened.

Presbyterians, Methodists, and Baptists preached side by side, something rare for the time. Whole crowds fell to their knees, trembling, weeping before the presence of God. James B. Finley, then a young man, left a firsthand account saying he had never seen anything like it before in his life.

The legacy is significant. Cane Ridge launched the “camp meeting” format that would spread across the American frontier for decades, and it is historically linked to the birth of the Restoration Movement (Stone-Campbell), the origin of today’s Churches of Christ and Christian Churches, denominations that now number in the millions in the United States.

The Ulster Revival (1859)

When news of the New York Prayer Revival (which we cover next) reached Northern Ireland through missionary correspondence and religious publications, prayer groups began to multiply in County Antrim, especially in Ballymena. Through 1859 the movement spread across all of Northern Ireland, with crowds that contemporary sources described as extraordinary by local standards.

The spiritual impact was deep and lasting. Whole communities saw a genuine change in their habits, with testimonies of conversions that endured for generations and shaped the Protestant evangelical identity of the region for decades.

Six Men in a Room and a Nation Transformed (1857–1858)

September 1857. Wall Street is in a panic; a severe banking crisis grips New York. A Presbyterian layman named Jeremiah Lanphier decides to organize a noon prayer meeting in a room at the North Dutch Church, in Manhattan’s financial district. He waits. No one comes. Slowly, six people arrive.

Week by week, the numbers grew. Noon prayer meetings multiplied across New York’s churches and halls, then across other American cities. Newspapers of the day estimated tens of thousands of weekly participants spread across several cities at once, and the secular press dubbed the phenomenon the “prayer revival.”

This is one of the best-documented revivals in American history. Unlike many earlier episodes, it was covered by the secular press of its own time. Historian Kathryn Long devoted an entire academic study to these journalistic sources, confirming that what began with six people in a room became one of the largest prayer movements ever seen in the United States. A reminder that God can transform a nation starting from a handful of faithful people willing to wait on Him.

Wales (1904–1905): A 26-Year-Old Ex-Miner and a Nation on Its Knees

Evan Roberts was 26 years old, a former coal miner studying for the ministry when, in November 1904, he began preaching in his hometown of Loughor, in industrial Wales. His approach was simple. In many services, he gave the whole meeting over to prayer and to the congregation’s spontaneous singing. The result was one of the most remarkable revivals ever recorded. In just over a year, the whole of Wales was swept by an unprecedented move.

The numbers confirm the scale of what happened. More than a hundred thousand people were converted within a few months, according to Welsh denominational records — a very high number for a country with just over two million inhabitants at the time. Churches filled beyond capacity. Pubs closed for lack of customers. Courts recorded a sharp drop in criminal cases. Football matches were canceled because players and fans were at revival services instead. Proportionally, it was one of the fastest and most complete social transformations ever documented in the history of a nation.

Journalist W. T. Stead traveled there specifically to cover the phenomenon for the Review of Reviews and published detailed firsthand accounts. A secular reporter who went to see for himself confirmed the scale of what was happening. The response was immediate and international, reported by the British and American press, and it is recognized as a catalyst for other awakenings around the world in the same period — including, according to missionary accounts, a direct influence on what would happen three years later in Korea, in Pyongyang.

Evan Roberts paid a heavy personal price for leading a movement of that magnitude, and years later withdrew from public ministry to rest. But the fruit he helped plant remained. Generations of Welsh people grew up shaped by the religious culture of that year, and the episode is still cited as one of the clearest examples of how a single revival can reshape a country’s spiritual character within months.

A Stable on Azusa Street (1906–1915)

William J. Seymour was the son of formerly enslaved parents, an African American preacher, and he was barred from preaching in a Los Angeles holiness church because of a conviction he held firmly: that the baptism of the Holy Spirit came with the gift of tongues. Expelled, he began leading prayer meetings in a private home on Bonnie Brae Street. In April 1906, participants began experiencing glossolalia.

What happened next is history. The group rented an old building on Azusa Street that had once been a Methodist church and later a stable and warehouse, and held services there almost continuously, three times a day, six days a week, for several years. In an America still segregated under Jim Crow laws, the Azusa Street building welcomed Black, white, and immigrant worshippers, rich and poor side by side — a living testimony to the gospel’s power to tear down human barriers.

Even the Los Angeles Times, a secular and openly skeptical newspaper, ran a story in 1906 describing the phenomenon in vivid — and dismissive — terms. That’s independent, contemporary journalistic proof of the real scale of what was happening in that rented building.

The long-term impact of this revival is of a different order of magnitude compared to any other episode on this list. By some estimates, Pentecostal and charismatic believers today number over 500 million worldwide, making it one of the largest families of Christians on earth — one of the fastest-growing branches of Christianity over the past century, born from a handful of people praying in a rented shed in Los Angeles.

Pyongyang (1907): The Night of Confessions

Yes, that Pyongyang. Before it became synonymous with something else, it was a Korean city under growing Japanese control. Protestantism, planted by American and Canadian Presbyterian and Methodist missionaries, was still growing slowly. Then Korean and Western missionaries, inspired by the Welsh revival, began praying for something similar in Korea.

In January 1907, during a ten-day Bible course at Jangdaehyeon Church, gathering about 1,500 people, the atmosphere began to shift. On the night of January 14, in a meeting led by Korean pastor Gil Seon-ju and American missionary William Newton Blair, participants began praying aloud simultaneously, amid public confessions of sin and a profound move of the Holy Spirit. It happened again on the following nights, and in the following months it spread across the whole peninsula.

The numbers speak for themselves. Korean Protestant converts jumped from a few thousand to tens of thousands between 1907 and the following year. The legacy is alive today. South Korea’s robust culture of early-morning prayer, with five a.m. services and “prayer mountains” devoted to fasting and intercession, traces directly back to this episode. Decades later, South Korea would become the country with the highest concentration of megachurches on the planet, including the largest Christian congregation in the world by membership — a direct fruit of that night of confession in Jangdaehyeon.

Two Sisters, One Blind, and the Hebrides (1949–1952)

Peggy Smith was 84. Her sister Christine, 82, was blind. They lived in the parish of Barvas, on the remote Isle of Lewis, in the Presbyterian northwest of Scotland, a region facing a worrying post-war spiritual decline among the young. The two elderly women prayed fervently, convinced they had received a specific biblical promise for their community.

At their request and that of other church leaders, evangelist Duncan Campbell was invited to preach in Barvas. On the night of his arrival, and in the weeks that followed, crowds gathered in churches, barns, and in the open air, in services that stretched from night into the small hours. The movement leapt from parish to parish across the Isle of Lewis and then to Harris.

Campbell left extensive records, including transcribed sermons and recordings. The social effect was dramatic and well documented by independent witnesses. Pubs and dance halls closed, and there was a sharp drop in local court activity for lack of criminal cases. A reminder that the persistent prayer of two elderly women, one of them blind, can move heaven and transform an entire island.

Balokole: The Revival That Survived a Genocide (from 1929)

Rwanda, 1929, the hill of Gahini. British missionary doctor Joe Church and Ugandan lay leader Simeon Nsibambi, who had for years sought a personal and communal revival, met, and together with the staff of a local hospital began a movement marked by radical public confession, community transparency, and an emphasis on a victorious life in the Spirit. The name stuck: Balokole, meaning “the saved” in Luganda. Through the 1930s and 1940s the movement crossed colonial borders, spreading through Uganda, Kenya, Tanganyika, and eastern Belgian Congo, reaching its peak at Gahini in 1933.

Joe Church’s personal papers are preserved today at the Henry Martyn Centre, affiliated with Cambridge University. Historians of the collection The East African Revival: History and Legacies have documented the movement using missionary and African primary sources.

It’s the most recent development that gives this whole list its most incomparable weight. Historical accounts document how the spiritual legacy of the Balokole sustained exiled Tutsi refugees after 1959 and, decades later, survivors of the 1994 Rwandan genocide. Even in the face of the darkest tragedy in recent African history, the faith planted decades earlier by that revival continued to be a source of strength, reconciliation, and hope for thousands of survivors. A testimony that God’s work stands firm even when human history fails catastrophically.

The Latter Rain Movement (1948)

February 1948, Sharon Bible School, North Battleford, in the frigid Canadian province of Saskatchewan. A group of students and leaders experienced intense phenomena: prophecies, the laying on of hands with specific revelations for individuals, healings — all interpreted in light of the “latter rain” of the book of Joel, a final outpouring of the Spirit before Christ’s return. The movement spread rapidly through independent congregations in the United States and Canada via traveling conferences.

At its 1949 General Council, the Assemblies of God in the United States formally condemned specific Latter Rain teachings as unbiblical, a decision preserved in denominational records to this day. Even though some of its practices generated legitimate debate within Pentecostalism itself, it is widely recognized that central Latter Rain ideas, such as the doctrine of the “five-fold ministry,” influenced and strengthened whole segments of the charismatic and neo-Pentecostal movement in the decades that followed.

From LSD to the Cross: The Jesus Movement

The late 1960s, California in the full swing of the counterculture. The Vietnam War, psychedelic drugs, mass spiritual experimentation. In the middle of it, thousands of young hippies, many of them former drug users, found in Jesus a real answer to the emptiness they had been trying to fill with substances. The epicenter was Calvary Chapel in Costa Mesa, pastored by Chuck Smith, who welcomed the long-haired, barefoot hippies without demanding they change their appearance before coming in — only their hearts.

The image that stuck in American culture: mass baptisms on Southern California’s beaches, rows of young people wading into the Pacific Ocean to publicly seal their new faith. In June 1971, Time magazine devoted an entire cover story to the phenomenon, “The Jesus Revolution,” with secular reporters documenting its growth among California’s youth.

Historian Larry Eskridge, in God’s Forever Family (Oxford University Press, 2013), traced how Calvary Chapel grew from a small congregation into a network of hundreds of affiliated churches. The impact went far beyond conversion numbers. The Jesus Movement is recognized as a direct catalyst for the contemporary Christian music industry and for an informal, youth-oriented worship style that became the standard in American evangelical churches in the decades that followed. Proof that the gospel wins over even the most resistant generations.

Asbury 1970: 185 Hours Without Stopping

Asbury College, today Asbury University, in Wilmore, Kentucky, already had a tradition of spontaneous revivals dating back to the start of the twentieth century, with episodes in 1905, 1950, and 1958. On February 3, 1970, during an entirely ordinary morning chapel service, a student gave a brief personal testimony. Other students decided to stay after the normal closing time.

What began as an informal extension turned into a continuous stretch of testimonies, confessions, and prayer that lasted 185 unbroken hours — more than a week without stopping. Teams of students later traveled to dozens of other American campuses and seminaries to share what they had experienced, spreading the movement across the country. It was a clear demonstration of how God can turn a routine chapel service into a wave of revival reaching an entire nation, planting a seed that would germinate again, with even greater force, 53 years later.

The Toronto Blessing (1994)

January 20, 1994, Toronto Airport Vineyard Church, Canada. Visiting pastor Randy Clark preaches at a service, and the congregation experiences an intense, unusual manifestation of the Holy Spirit. What was supposed to be a one-time service turned into near-daily meetings for years, drawing visitors from dozens of countries — the international phenomenon that came to be called the “Toronto Blessing.”

Secular journalists covered the phenomenon up close, in person, over the following years, confirming its real scale. The movement sparked debate within the charismatic movement itself over how best to discern and steward such intense manifestations — a sign that the church took both the spiritual experience and the pastoral care surrounding it seriously. Despite that debate, the phenomenon spread to thousands of charismatic churches around the world through the 1990s, leaving a lasting impact on how many congregations experience God’s presence in their services.

Brownsville: Five Years of Nightly Services (1995–2000)

June 18, 1995, Brownsville Assembly of God, Pensacola, Florida. An ordinary Sunday service. Visiting pastor Steve Hill preaches a sermon that provokes an unusually intense response of repentance. The church decides to extend the services one more night. Then another. And another.

The result: services held almost daily, with varying intensity, for about five years — one of the longest periods of continuous revival documented in twentieth-century America. The church itself recorded millions of visitors over the period. The Pensacola News Journal covered the movement’s impact even on the city’s economy and traffic, while also raising pointed questions about its finances and claims.

During the revival, the Brownsville Revival School of Ministry was born, training leaders who would go on to spread across churches around the world, multiplying the fruit of that single night in 1995 across generations of workers.

The Argentine Revival

Argentina, in the aftermath of dictatorship, amid a hyperinflation crisis that shattered families throughout the 1980s and 1990s. It was in that setting of crisis that evangelists such as Carlos Annacondia filled open-air campaigns, drawing tens of thousands of people a night in different cities, with a strong emphasis on divine healing and deliverance from practices popularly associated with spiritism and the occult in Argentina. Claudio Freidzon, of Rey de Reyes Church in Buenos Aires, led a parallel movement of great reach.

Independent researchers documented the real numerical growth of the country’s evangelical and Pentecostal churches over those two decades. In one of the nations hardest hit by economic crisis on the continent, the gospel found fertile ground and produced one of the largest revivals in Latin America.

The Church That Grew in Hiding: China

After 1949, and especially after the Cultural Revolution (1966–1976), Chinese Christianity was pushed underground. Small, unregistered house churches, organized around lay leaders, operated under real legal risk. No public crowds, no chapel service turning into national news — just quiet, steady growth, decade after decade, under one of the most religiously restrictive regimes on the planet.

The numbers, once researchers were finally able to estimate them, stunned secular scholars. The Pew Research Center calculates that Chinese Protestantism grew substantially from a small base in 1980 to tens of millions of believers in the following decades, even amid decades of active persecution. It’s one of the most remarkable religious growth stories of the twentieth century, and proof that no state restriction has been able to contain the advance of the gospel.

More recent Pew Research studies indicate that the pace of growth has leveled off in the last few years, but the base of tens of millions of believers built up in the midst of hiding remains one of the most powerful testimonies of the church’s perseverance in the modern world.

Nepal: From a Few Hundred to More Than a Million

Until the mid-twentieth century, Nepal was a Hindu kingdom that kept its doors largely closed to foreign Christian missions, with laws that criminalized religious conversion itself. The numerical starting point was tiny — a few hundred registered Christians. From the fall of the formal Hindu monarchy in 2008, when the country officially became a secular republic, growth accelerated dramatically.

Today, independent estimates, including Nepal’s own national censuses, put the number at hundreds of thousands to more than a million Christians. It’s one of the most remarkable missionary advances of the modern era.

Accounts gathered by researchers and journalists who focus on religious persecution frequently record conversions in isolated rural communities linked to testimonies of physical healing, in a context where access to formal medicine has historically been very limited. Even facing laws that still restrict religious freedom today, the Nepali church continues to grow — a living testimony that the gospel advances even under persecution.

Asbury 2023: When TikTok Met an Altar

February 8, 2023, Hughes Auditorium, Asbury University, Wilmore, Kentucky. The same campus as 1970, now 53 years later almost to the day. A regular chapel service ends. A small group of students decides not to leave. They stay there, praying, singing, with no program at all. University president Kevin Brown sends out a short message: there’s worship happening in Hughes, everyone is welcome.

What happened next has no precedent in any of the nineteen previous episodes on this list, because none of them happened in the age of social media. The news went viral within hours. In the days that followed, the small auditorium, and then extra spaces lent by the neighboring Asbury Theological Seminary, began receiving thousands of visitors a day. The event lasted sixteen days straight, from February 8 to 23, with estimates of 50,000 to 70,000 cumulative visitors, coming from more than 200 different academic institutions and several countries, according to the university itself.

The scale was documented in a way no historical revival ever had been before. The Washington Post and other major outlets sent teams to the scene, along with student journalists from Asbury’s own campus paper.

The phenomenon jumped to other campuses that same February — Samford, Cedarville, Cumberlands, and other institutions, carried by students who visited Wilmore and returned home transformed. Participants and the university’s own leadership highlighted something notable about this episode: its hallmark was not extreme physical manifestations, but a deep simplicity, peace, and genuine worship, in a generation — Gen Z — often described as the most distant from faith in recent American history, and which there showed the opposite.

Conclusion: God Continues to Act in History

Twenty episodes, four continents, three centuries. The pattern that emerges is no coincidence. Again and again, God used ordinary people: a Welsh ex-miner, two elderly Scottish women, a group of six men in a room in New York, a small group of students who wouldn’t leave a chapel service. Through them, He unleashed movements that transformed cities, nations, and whole continents.

These episodes are not pious legends without historical grounding. The meetings happened, on specific dates and in specific places. The crowds really gathered, often recorded by the secular newspapers of the time, not only by religious sources. The churches grew numerically, with denominational records and, in many cases, government censuses to confirm it. The long-term social and cultural impacts are recognized and studied by secular historians at universities like Yale, Cambridge, and Oxford, with the same rigor they would apply to any other major historical movement.

Pentecostalism, born largely out of Azusa Street, is today one of the fastest-growing religious branches on the planet, with hundreds of millions of adherents. Korean Christianity, shaped by the prayer culture of Pyongyang 1907, produced some of the largest congregations in the world. China’s underground Christianity grew, despite decades of persecution, to numbers secular researchers recognize as one of the most significant religious-demographic phenomena of the twenty-first century. Wales, in just a few months, saw more than a hundred thousand people turn to Christ, in one of the fastest and most complete spiritual transformations ever recorded in the history of a nation.

These twenty episodes, from the Moravians of Herrnhut to the Asbury campus in 2023, show a promise fulfilled again and again across three centuries. Where God’s people humble themselves and pray, revival comes, and history records it. May that same promise keep being fulfilled in our own day — in Brazil too.

Frequently Asked Questions

What was the greatest revival in history? It depends on the criterion. In long-term demographic impact, Azusa Street (1906) usually wins, for having given rise to worldwide Pentecostalism, which today numbers in the hundreds of millions. In the proportional transformation of an entire nation in the shortest time, the Welsh Revival (1904–1905) is the most commonly cited example, with more than a hundred thousand conversions in a few months. In the sheer size of a single in-person event, Cane Ridge (1801) and Asbury 2023 are among the most remembered.

Did Azusa Street really happen? Yes, and it’s very well documented. Beyond religious sources, the secular Los Angeles Times covered the event as early as 1906, independently confirming the scale of what was happening — even while describing it in dismissive terms.

What is the evidence for the Welsh Revival? It’s strong and comes from multiple angles. Welsh denominational records confirm more than a hundred thousand new members between 1904 and 1905, secular journalist W. T. Stead traveled there and documented the phenomenon in person, and the British press of the time recorded pub closures, a drop in criminal cases, and empty sporting events — a full picture of a transformed nation.

What do historians say about Brownsville? They recognize it as one of the longest continuous revivals of twentieth-century America, well documented by local news coverage — a movement of repentance and consecration that formed a whole generation of Christian leaders, even as some financial and behavioral claims drew scrutiny from local journalists.

Was the Toronto revival genuine? The event itself, as a large-scale social and religious phenomenon, is very well documented by secular journalists who covered the meetings in person over several years. It sparked important reflection within the church about how to discern and steward intense spiritual manifestations with pastoral maturity.

How do historians investigate revivals? They document whether the event happened, its scale, its contemporary press coverage, and its lasting social impact, all with the same rigor applied to any other historical landmark. Church growth, drops in crime, behavioral changes across a whole city — all of that is measurable and has been measured, often by secular sources and even by governments.

What distinguishes a revival from a broader religious movement? “Revival” usually describes a concentrated period of spontaneous spiritual intensification in a community, marked by public confession, intense prayer, and rapid numerical growth, generally traceable to a clear starting date or event. “Movements” that are longer and more diffuse, like the continuous growth of the church in China and Nepal, are also genuine fruit of God’s work, even though they unfold over decades rather than weeks.

Did Pentecostalism begin at Azusa Street? The first documented modern episode of glossolalia actually happened earlier, under Charles Parham, in Kansas, in 1901. But Azusa Street is recognized as the event that launched Pentecostalism as a worldwide phenomenon, thanks to its duration, visibility, and the periodical The Apostolic Faith, which was distributed internationally.

Does God still bring revival today? Recent history answers for itself. Nepal, China, and Asbury 2023 show that the same pattern keeps repeating in the twenty-first century. Evangelical tradition has always believed so, and the historical record gathered in this article, spanning three centuries and four continents, is an invitation for every reader to seek that same move of God today as well.
