The central and divine thought of the Scriptures is that God is seeking a divine building as the mingling of Himself with humanity. He is seeking a living composition of living persons redeemed by and mingled with Himself.
After His creation, God began and is still carrying out the work of the divine building. Even today God is doing the work of the divine building, which is to mingle Himself with man. We preach the gospel not merely to win souls or save souls from hell but to minister God Himself through the Spirit to man so that God can be mingled with man. In this way we gain the materials for the divine building. Likewise, we minister Christ to the saints so that they can be mingled and built up together with Christ. This is the basic and central thought behind what we do. (Witness Lee, The Building of God, ch. 1)
