I found a copy of this old presumably out-of-print book by Dr Ja Shil Choi, the late mother-in-law of Dr Yonggi Cho, who is the pastor of the massive church in Seoul, Korea – Yoido Full Gospel Church. Dr Choi was the founder of Prayer Mountain in Korea.
This book deals with the power of God that may be released through fasting and prayer. It contains many wonderful testimonies. I saw no copyright notice on it, so I have taken the liberty of publishing it here on this site to inspire the current generation with wisdom from a great woman of God.
