Book excerpt: This book started from the shock, by the time the author had grown up and developed a certain degree of self-consciousness during his childhood, of discovering that "I don't know who I am (how humans came to exist)“ and that ”even though, I am living my life calmly as if I don't need to know that fact“ From that day on, I have started a lifelong struggle to find the truth about these questions - “How did I and this world come into existence? Does God who created me and this world exist? If such God exists, why did God create humans and this world? How should I live?”, and the accumulation of that enlightenment is this book. This book was written with standards on interpreting human history and individuals who inevitably stand in the history of humanity. This book reveals that although human history is the story of people, creature-man is not the subject of this human history, but the Creator God who creat and governs this world and man, and that human history should be interpreted as a process that God is leading to personally fulfill His purpose of Creation. The main content of this book is the story of a subjective process that integrates the past, present, and future led by God. And, as a conclusion, the author recommended that everyone should realize that his present life that he just lives and dies without realizing how he came to exist is not the real-life based on the truth, and return to his original place of the real truth-life(living as a God’s child with Father God, infinitely creating God's good works within himself, and enjoying eternal life and the greatest happiness) as he was created. It is revealed that this is the purpose of God's creation of the heavens and the earth, and at the same time, that it is a life based on the truth that created human beings should live. This invitation is the ultimate purpose of writing this book. main contents of this book 1. God, the Creator who created this world and man, exists / Who is God? 2.
