The apostle Paul instructs us, "Ye are the body of Christ, and members in particular" (1 Corinthians 12:27). He says more specifically, "As the body is one, and hath many members, and all the members . . . being many, are one body: so also is Christ" (12:12).
Paul is telling us, in essence, "Take a look at your own body. You have hands, feet, eyes, ears. You're not just an isolated brain, unattached to the other members. Well, it is the same way with Christ. He is not just a head. He has a body, and we comprise its members."
The apostle then points out, "We, being many, are one body in Christ, and every one members one of another" (Romans 12:5). In other words, we are not just connected to Jesus, our Head. We are also joined to each other. The fact is, we can't be connected to Him without also being joined to our brothers and sisters in Christ.
Paul drives this point home, saying, "The bread which we break, is it not the communion of the body of Christ? For we being many are one bread, and one body: for we are all partakers of that one bread" (1 Corinthians 10:16-17). Simply put, we are all fed by the same food: Christ, the manna from heaven. "The bread of God is he which cometh down from heaven, and giveth life unto the world" (John 6:33).
Jesus declared, "I am the bread of life . . . I am the living bread which came down from heaven . . . he that eateth me, even he shall live by me" (John 6:35, 51, 57). The image of bread here is important. Our Lord is telling us, "If you come to Me, you will be nourished. You will be attached to me, as a member of My Body. Therefore, you will receive strength from the life-flow that is in Me." Indeed, every member of His Body draws strength from a single source: Christ, the Head. Everything we need to lead an overcoming life flows to us from Him.
