The purpose of this book is to appeal to those people who believed in God like me, but because of everyday problems plunged into worldly vanity. This book will help you open your eyes to the truth of the Christian faith. It has been 30 years since I decided that I would never again follow the lead of this world, where sin and the power of darkness reign. My goal is to help you protect yourself from many obstacles in spiritual development. God changed me beyond recognition. I happened to preach in Korea, Japan and even Australia. I never thought that I would have to write this book, moreover, in English, because I have a special relationship with English. At the request of Russian sailors, I translated this book into Russian. After God healed me from an incurable disease supernaturally, joy overwhelmed me. This was a good reason to write this book.
