Watchman Nee emphasizes the Christian life as a spiritual warfare, focusing on the necessity of understanding the distinction between the spirit, soul, and body. He highlights the importance of the cross of Jesus as central to overcoming sin, the world, and the devil. The sermon encourages believers to engage in spiritual cultivation through prayer, faith, and the application of biblical teachings, particularly from Romans 6. Nee asserts that true victory in the Christian life comes from recognizing and differentiating the spiritual from the self. This message serves as a guide for all Christians seeking to deepen their spiritual walk and effectively combat spiritual challenges.

The contents of this book were published in June 1927. The original Chinese title was, literally translated, The Details of Spiritual Cultivation. The present English title was provided by the author himself on the title page of that book. The original book was composed partly of messages translated from English by Brother Watchman Nee and partly of messages written by him in the years prior to 1927. Some of the chapters first appeared in the early issues of The Present Testimony magazine in 1923. The following is an announcement that appeared in the March 1927 issue (No. 15) of The Christian magazine. It states the nature of the book: A clear book on guiding man to a pathway of spiritual edification; a required reading for all those who desire to overcome sin, the world, and the devil. The whole book is divided into eighteen chapters, with three hundred pages and over a hundred thousand words. From its beginning to its end, it has the cross of the Lord Jesus as the center. This book pays special attention to the teaching of Romans 6. It details the way to differentiate the spiritual part from the self in our life. There are also clear teachings concerning the way to pray, to overcome the devil, and to engage in spiritual works. This book should not only be read but also studied by all God's children. All those who buy this book will continue to receive fresh light, even if they read it once every month. The book was published by the Bible Truth Depot, P.O. Box 323, Shanghai (also known as the Shanghai Gospel Bookroom) and sold for forty-five cents paperbound and seventy-five cents clothbound.
