In this sermon on Romans 12:3–5 titled “The Body of Christ,” Dr. Martyn Lloyd-Jones teaches the principle that everything is of grace. This principle ought to cause one to think soberly, not more highly. Consider the nature and parts of the human body and see this applied towards one’s position in the Christian church. A body has an organic unity that is vital. No one can put themselves into the body of Christ; only the Lord can add to the church. There is great variety and unity in the body. There is a different function for each member and this must not be forgotten. Christians must not envy one another for the positions each is granted. Some parts are not spoke of, but are essential to the working of the whole of the body. If one thinks of their gifts as independent, they should remember that their gifts are not for themselves but that they are a part of the whole and serve the whole. All are subservient to the head and they don't decide what they want to do but Christ does. The listener is encouraged to be ready to obey His every command and be at His service, standing amazed that they have any place in this body at all.
