INTRODUCTION

YOIDO FULL GOSPEL Church, the church I pastor in Seoul, Korea, with its 750,000 members, is the world's largest church. Every month as many as seven hundred new converts are being saved from Buddhism, secularism, and nominal Christian backgrounds.

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.

ristianity.Before the church was born on the Day of Pentecost, Luke wrote, "And [the disciples] were continually in the temple, praising and blessing God" (Luke 24:53). In the Book of Acts, Luke further amplifies what the disciples were doing: "These all continued with one accord in prayer and supplication" (Acts 1:14). The church was born when the Holy Spirit descended during a time of concentrated prayer.
