Church Growth and the Missing Factor

Dr. David Yonggi Cho has the largest church in the world. He said, No where in the world are there more people praying and fasting. I believe there is a correlation between the magnitude of prayer, continuous revival and church growth in South Korea. At the moment the church in South Korea has 875,000. At one time the church was growth so fast Dr. Cho had to plant 5000 people and pastor per Sunday because of the lack of space. Some have speculated if you add up  his church plants in South Korea  and his church , the number would exceed 3.5 million people. In His book, " Prayer: Key to the Revival" he said, " Our people have been taught  the central nature prayer so they pray over everything. They fervently pray for the church, the nation and the continuation of revival in Korea and throughout the world. They also, pray for potential new converts SO THAT THE CHURCH MAY CONTINUE TO GROW. We have learned that we are at war against Satan. Out battlefield is the hearts of all men and women. Our goal is that all may come to the saving grace of our Lord and Savior Jesus Christ. Therefore, we plan carefully; we have a strategy, we have a plan and we execute the plan like a well trained army. Yet, most importantly we bathe our plans in prayer so that God may breath His breath of life into our efforts and they will be fruitful. Cho, goes on to say, "  I have not followed a secret formula in the mighty church growth we are experiencing. What I have done is simply take the Word of God seriously. There is no question in my mind that what has done in Korea can also be duplicated in every part of the world. The Key is prayer"  What are you thoughts about Pastor Cho's statements regarding church growth and prayer.
