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.
