The Body of Christ is manifested on earth, not in heaven. The church as the Body of Christ is on earth. We have to express this Body while we are on earth. Although the Head is in heaven, the Body and the Head are one. Apparently, saved ones are being added to the church. But as far as its spiritual reality is concerned, no one has ever joined the church. The Body of Christ grows by itself from within. It grows continually out of the Head. The church is simply the extension of the Body of Christ on earth. The church dwells on earth but comes out of the heavenly Head. At the same time, it is a Body in oneness with the Head.
