The main revelation of the Bible is that God wants to enter into man to be his life that He may have a group of people to express Him. The way to take God as our life is to enjoy Christ by partaking of Him as the tree of life. Only when we partake of Christ can we live by Him, that is, live Him out.
In Living Christ Witness Lee shows us our need to take Christ as life and to live Him. Since the time of the fall, man has lived by the tree of the knowledge of good and evil, including many seemingly good items of culture and religion which serve as substitutes for Christ and replace Him. As believers, however, who are joined to the Lord as one spirit, we can enjoy Him as our food, drink, and breath by praying unceasingly to live Him out every day.
