Jakarta has become the most populous city on Earth. In a report released on November 18, 2025, the United Nations put Greater Jakarta, in Indonesia, at nearly 42 million people, ahead of Dhaka, Bangladesh, with almost 37 million, and Tokyo, Japan, with 33 million. Tokyo, which had led the ranking since 1955, is now third.
Greater Jakarta reaches far beyond the city proper of about 10.7 million, and it climbed in rank because the UN changed how it counts cities, measuring dense, connected urban zones and lowering the size threshold for what qualifies. The trend behind the ranking is plain in the numbers: the number of megacities, urban areas of 10 million or more, has grown from 8 in 1975 to 33 in 2025, and 19 are in Asia. Cities now hold 45 percent of humanity, and through 2050, two-thirds of the world's population growth is expected to happen in them.
In the central districts, people live packed at around 21,700 to a square kilometer. Five times a day, the Adhan sounds across Indonesia. It's a call heard by more Muslims here than in any other country, an estimated 240 million people, the largest Muslim population in the world. The streets run on the ojek, the motorbike taxis hailed through apps like Gojek and Grab, weaving between cars. Food is sold in the open air from small roadside stalls called warungs, including nasi goreng, the fried rice many call the national dish, and sate, charcoal-grilled skewers.
The city also faces real pressures: about 40 percent of Jakarta lies below sea level, and the northern districts continue to sink, as Indonesia builds a new capital, Nusantara, on the island of Borneo. In addition, Jakarta's traffic ranked 24th among the world's most congested cities in a 2025 index.
In the face of these challenges, how can the gospel of Jesus reach 42 million people in one dense, low-lying, traffic-bound city, and then across a nation of more than 17,000 islands and more than 700 languages? The scale only widens. Joshua Project, a mission-research group, estimates that about 3.4 billion people, more than four in ten alive today, have little or no access to the gospel. For most of the church's history, reaching them at that scale was simply out of reach.
The same forces are changing what is possible. The very things that make Jakarta feel unreachable, its density, its youth, and its phones, are what place an answer within reach. Indonesia's median age is about 30, and its young millions live on their screens. The gospel of Jesus, which once crossed the water by ship and by a printing press, can now travel in a video shared between two friends. That is where Hope Channel comes in: to make a message worth sharing and to place it where people already are.
Hope Channel is the media arm of Christianity for reaching the unreached, and it frames its task as reaching one billion people with the message of eternal hope by 2030. Ninety channels carry it, each in a local voice and a local language. Hope Channel Indonesia broadcasts in Bahasa Indonesia under the slogan "Televisi yang mengubah hidup Anda" [Television That Changes Your Life], and anyone can view its free YouTube channel, @HopeChannelIndonesiaTV. Its leaders are careful to say media is not the whole of it. "Even if there are members who are not on social media, they are in a social environment," said Gary Krause, Adventist Mission director. "They can take a cup of soup to a neighbor...that human connection, which nothing can ever replace."
This is not the first time the gospel of Jesus has traveled to reach these islands. Christianity has a long history in the Indonesian archipelago, including Portuguese Catholic missions in the Moluccas beginning in the 16th century and later Protestant work under Dutch rule. Ralph Waldo Munson, already fluent in Malay, stepped ashore at Padang, Sumatra, on January 1, 1900.
With no operating budget, the Munsons supported themselves by opening an English school and a small clinic. Nearly a decade later, in 1909, Munson set up a printing press in Sukabumi, West Java, and its quarterly carried the name Messenger of Truth. His first convert, Immanuel Siregar, became a pastor, and in April 1911 the press moved to Batavia, the city known today as Jakarta. Hope Channel Indonesia, founded in 2010, opened a new studio in that same city in June 2025. The gospel reached the future megacity through a relocated press; it returns to it now through a screen.
Jakarta is a new kind of frontier, yet the gospel of Jesus has found its way there for more than a century. If reaching the world once looked impossible, it may be that it has never been this close to possible, or this personal. Behind the figure of 42 million are 42 million faces, each one known and wanted by Jesus. The invitation runs to anyone willing to take it up: to pray for a city like Jakarta, and to use whatever is already in hand, a talent, a phone, a friendship, or cup of soup to help the hope of the gospel reach one more of them.
