The fellowship of the Body of Christ is very similar to the circulation of the blood in our body. We have been enlightened to see that Christ has a Body and that we are members of His Body, that is, members of Christ Himself. Just as our physical body has many members, Christ's Body also has many members. And just as a man has only one body—this is a principle ordained in God's creation—Christ also has only one Body. If we do not understand the church as the Body of Christ, we should simply look at our own body. We can understand Christ's Body by knowing our own body. I have learned a great deal concerning the Body of Christ by learning to know my own body. If we learn to know our body, we will know the Body of Christ.

The circulation of the blood is the fellowship of our body. The fellowship of Christ's Body also is a kind of circulation. In our physical body we have the circulation of the blood, but Christ's mystical Body does not have blood. The fellowship in Christ's Body, then, is the circulation of the Spirit. The Spirit today is the "blood" in Christ's Body. If there were no blood in our body, our body would be dried up and would be dead. Likewise, if Christ's Body did not have the Spirit, it would be like a corpse. Thus, the fellowship of the Body of Christ is simply the circulation, the current, of the Spirit—not the Holy Spirit or the Spirit of God, but the Spirit. In the New Testament the Spirit denotes the consummated Spirit, the Spirit who has been consummated, compounded, and mingled, and who is now dispensing. In this Spirit there is divinity, that is, God's divine nature, and there is humanity, that is, man's human nature. There is also Christ's person, Christ's wonderful, all-inclusive death, and Christ's empowering resurrection with His ascension. All these elements have been compounded into this one Spirit. When this one Spirit is circulating within the Body of Christ, divinity, humanity, Christ's person, Christ's death, and Christ's resurrection all are circulating. How wonderful this is!

The circulation of the blood is very important to our physical body. This circulation carries nourishment to every part of our body, and it also causes our body to be cherished. At times we may need to do some physical exercises to improve the circulation in our body. This may cause us to be more healthy. Romans 10:12 says that whenever we call on the name of the Lord, the Lord becomes rich to us. I have discovered that the more we call on the Lord with a loud voice, the more our spirit is released and the more we are healed and strengthened. Such calling on the Lord will make us very healthy, because to call in this way is to exercise. If we are always quiet and shut up within ourselves, we will be very weak. But if we call, "O Lord Jesus! O Lord! O Lord, Amen, Hallelujah!" for ten minutes, the Lord will become rich to us. We will have joy, and eventually we will have strength. The joy of the Lord will be our strength (Neh. 8:10). I have learned the secret of calling on the name of the Lord. The Lord is rich to all who call on Him. To call is not merely to pray. The Greek word for call means to cry out, even loudly. In certain situations it would not be appropriate for us to call on the Lord loudly. However, when we are in a proper situation to do so, we should call loudly, "O Lord Jesus! Amen!" By calling on the Lord in this way, we will enjoy the riches of Christ, and we will be strengthened. This is because our calling on the name of the Lord causes the Spirit to circulate within us. This circulating Spirit is the compound Spirit, who includes divinity, humanity, Christ's person, Christ's death, and Christ's resurrection. The riches in this compound Spirit are unsearchable. When this Spirit circulates within us, we enjoy all Christ's riches. This circulation is the fellowship of the Body of Christ.
