This is a complete presentation on the workings of the human spirit and soul and body. The book aims at delivering people from the tyranny of self-life with its carnality and from the domination of the passions and lusts of the flesh. It attempts to lead them to the full salvation of Christ. It is not to be taken as a manual but as a guide to true spirituality. It is recommended that this three-volume work be listened to quickly once.

In this little volume of collected messages selected for the unity of their subject matter and given by the author through years of faithful ministry, Watchman Nee attempts to show us the reality of the body of Christ. He proves to us that the body of Christ is founded on life and life consciousness.

Authority is a tremendous thing in the universe, nothing overshadows it. God's throne is established on His authority. God's authority represents God Himself. God alone is authority in all things; all the authorities of the earth are instituted by God. It is therefore important for us who desire to serve God to know the authority of God.

Watchman Nee's thesis in this book is that Christ came to mankind by way of the cross, and only by this same way can we know him. At the source of all spiritual things, he says, stands the cross.

"My Father worketh even until now, and I work," declared the Lord Jesus while on the Earth (John 5:17). Having thus laid the foundation of the work, Christ commands his Church to fulfill it in the power of the Holy Spirit. We Christians who are the many-membered body of Christ have a pressing need to know how to serve according to God.
