This book presents a vision of Christ and the church. It then goes on the emphasize the need to experience this Christ as the Spirit in our spirit and to practice the church life on the ground of oneness.

Ephesians reveals three great items in the New Testament: the Body of Christ, the Spirit, and the new man. Each of these items is uniquely one and ultimately related to Christ. The Body of Christ is the fullness of Christ, the One who fills all in all. The Spirit imparts the divine life, which contains the elements of Christ's divinity, humanity, death and resurrection, into the members of His Body, and this impartation of life produces a corporate expression of Christ that is displayed in and through the one new man. In One Body, One Spirit, and One New Man Witness Lee shows how the Body of Christ becomes His fullness through the believers' enjoyment of Christ. As we experience His boundless and immeasurable riches through the Spirit, we are reconstituted as members of His body, and as we take Him as our life and our person, the one new man in the universe comes into being in a practical way.

The most important work of God on earth is the speaking out of His word through man. In the Old Testament God's word was released through the ministry of the prophets, and in the New Testament it was released through the ministry of the Lord Jesus and later through the apostles. Even though God is pleased to allow us to speak His word, the greatest measure of our usefulness as a minister of the Word is not the amount of our Bible knowledge or even the ability to eloquently present the truth; rather, it is the degree to which our inward parts have been molded and shaped by the Holy Spirit. The Ministry of God's Word contains a series of messages given by Watchman Nee in 1948 and 1949 after nearly thirty years of ministry. These messages are deep, profound, subjective, and full of light, revealing both the depth of his experience and extent of our need to open to the Holy Spirit's inward operation.

This book traces the progressive revelation of God from His being the "bachelor" God in Genesis 1:1, through His incarnation, redemption, and indwelling, to become the incorporated God. This incorporated God is the Body of Christ. The focus of this book is to help the believers see the vision and enter into the experience of the Body-Christ in the church life today.
