Out of the 10 largest churches in the world, South Korea has 6 of them. A director of one of the churches said that the churches in the area come together to pray in the morning.

“As I write this book, my church is growing at the rate of 12 000 new converts every month. These new souls are being saved from Buddhism, secularism and nominal Christian backgrounds. No one can argue that this unprecedented rate of church growth is due to the revival fires now sweeping over Korea.
The present membership of our church is approaching 400 000. By the end of 1984, at our present rate of growth, we shall have in excess of 500 000 active members.
How could a church grow this large?
Is it possible for other countries to have this kind of revival? I am convinced that renewal is possible anywhere people dedicate themselves to prayer.
It is because I believe in revival and renewal that I have written this book. It has been historically true that prayer has been the key to every revival in the history of Christianity.
In 1982, we led 110 000 people to Christ. Out of those new converts, we were only able to absorb 60 000 members. Therefore we gave other evangelical churches a total of 50 000 members.
In 1983 we had a total of 120 000 new converts. Why are so many people being saved within a single church? We have seen the importance of developing and keeping a prayer life. If we stop praying, the revival will wane (decline or fade). If we continue praying, I believe all of Korea can be saved.
I believe that the same level of revival can be experienced in your church. There is no land too hard for the Holy Spirit to work. There is no church too dead. There is no country too closed to the gospel. The answer is prayer”
