The Church was formed out of a little company of 120 men and women who were gathered together praying in the Upper Room at Jerusalem. [Footnote: Acts i. 14, 15.] Suddenly they heard a wonderful sound and saw a heavenly vision, and they were all filled with the Holy Ghost; and before the day was over that little company increased to the number of 3,000 souls. How many does it number now? No one knows, but it is a "multitude which no man can number." [Footnote: Rev. vii. 9.] Some are already in glory, some are still on earth, but it matters not where they are, they belong to the "whole family" of God "in heaven and in earth." [Footnote: Eph. iii. 15.] On the Day of Pentecost, when the Holy Spirit was poured out, His special work was to create a new thing--it was then that the Church of God was formed into one Body by the Holy Spirit, "For, as the body is one and hath many members, and all the members of that one body, being many, are one body, so also is Christ." [Footnote: I Cor. xii. 12, 27.] "Now ye are the Body of Christ and members in particular," that is, individually, for every saved soul is a member. The Church is a living body united to Jesus Christ, for He is the living Head of the Body. He needs His Church just as much as His Church needs Him. It is the Holy Spirit who unites us to the risen and glorified Christ Who is the Head, and then He unites us to one another in Him. It is a _living_ union, because we pass through death into the resurrection life of Christ, for by "One Spirit we are all baptized into One Body, and we have all been made to drink into that One Spirit." [Footnote: I Cor. xii. 13.] The Holy Ghost sustains the life of the Church. In Him we live and move and have our being. As the bird lives in the air, as the flower lives in the sunshine, so we live in the Spirit, and when we drink in His fulness there is growth and fruitfulness. Have we ever felt this need of drinking into that One Spirit? Everything connected with the true Church of Christ must be spiritual, it is this which is being lost sight of in the present day, and it is the reason why there is so little power and so few conversions. Have you ever tried to understand why the Church is called "the Body of Christ"? Think first about your own body. It is the only part of your real self that can be seen. I cannot see your heart or your thoughts, but I know what your thoughts are by your words, and what you feel by the look of joy or sorrow in your face, and by the way you go about. It is by your body that your real personality is made known to others; what you really are would never be seen unless your body made it known. In the same way the Church is the Body in order to make Christ known in the world. He is hidden from our view, He is unseen, but He manifests Himself and shines out through us, and He sends us to carry His messages and to do His Will.
