In our time, few people doubt that the world was created by the Creator (God, Being, Life). However, without understanding what God is, it is impossible to understand who he is as a person, why he appeared on earth. The book presents the results of a philosophical and psychological study of the Bible conducted by the author, which made it possible to understand God (Life) as a process of gradual development of the need to be, to identify the mechanism of development (as the interaction of different forms of Life with each other), to trace the ways and means of the development of Life. All this knowledge is set forth in Scripture. The “verbs of eternal life” were brought to earth by Jesus Christ, who with his whole life and his deeds showed the way to eternal life. It is precisely as a theory and practice of building true life on earth that the New Testament must be read. Based on the knowledge set forth in the Bible, the author developed the “Theory of Life as a comprehensive theory of development”, as a new methodology of knowledge, building society, and human formation.
