At the time of regeneration, all believers receive the divine life and are begotten as children of God. Yet, this life most grow and it does so by regulation unto maturity and function. This regulation comes from revelation and issues in obedience. This word is crucial for our progress and training in the divine life for our maturity and function in our living and service to God.

When God created man, He placed him before two trees: the tree of the knowledge of good and evil and the tree of life. In warning man to avoid the tree of the knowledge of good and evil, God indicated His desire for man to eat of the tree of life, signifying that man should receive God as his life supply. Witness Lee unveils in The Tree of Life that God is not looking for well-behaved Christians; He is looking for those who will experience and enjoy Christ as the reality of the tree of life.

In the Lord’s recovery during the past five hundred years the church’s knowledge of the Lord and His truth has been continually progressing. This monumental and classical work by Brother Witness Lee builds upon and is a further development of all that the Lord has revealed to His church in the past centuries. It is filled with the revelation concerning the processed Triune God, the living Christ, the life-giving Spirit, the experience of life, and the definition and practice of the church. In this set Brother Lee has kept three basic principles that should rule and govern every believer in their interpretation, development, and expounding of the truths contained in the Scriptures. The first principle is that of the Triune God dispensing Himself into His chosen and redeemed people; the second principle is that we should interpret, develop, and expound the truths contained in the Bible with Christ for the church; and the third governing principle is Christ, the Spirit, life, and the church. No other study or exposition of the New Testament conveys the life nourishment or ushers the reader into the divine revelation of God’s holy Word according to His New Testament economy as this one does.

"The entire Bible, from Genesis to Revelation, shows us that God is our enjoyment. God also has His fullness (Eph. 3:19b). He is full for us to enjoy. His fullness is the expression of the riches of Christ, and the reality of Christ is in the Spirit. We know this by the revelation of the Word. The riches of Christ are revealed in the Word. Furthermore, we can realize God as our enjoyment in our spirit (John 4:24)."

“We must realize that we Christians are a meeting people. A Christian is a meeting person. Without meeting, there is no Christian life and no church life. It is rather difficult for any Christian to grow without attending the meetings. There is no way for any Christian to serve God without meetings, and it is impossible for Christians to express Christ if there are no meetings. The church life is a meeting life.” In How to Meet Witness Lee offers much precious and practical guidance related to the biblical way to meet as Christians.
