Tozer argues that modern Christianity has lost its sense of awe and wonder in the face of God's majesty, and that many believers have reduced God to a kind of cosmic vending machine, to be approached only for personal needs and desires. He believes that a true knowledge of God requires humility, reverence, and a willingness to accept the mystery and transcendence of God.The book is structured around a series of meditations on the various attributes of God, such as His omnipotence, omniscience, and holiness. Tozer's writing is characterized by its poetic language and its ability to inspire a sense of wonder and awe in the reader.
