3For through the grace given to me I say to everyone among you not to think more highly of himself than he ought to think; but to think so as to have sound judgment, as God has allotted to each a measure of faith. 4For just as we have many parts in one body and all the body’s parts do not have the same function, 5so we, who are many, are one body in Christ, and individually parts of one another.
3For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith. 4For as we have many members in one body, and all members have not the same office: 5So we, being many, are one body in Christ, and every one members one of another.
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.
Dr. Martyn Lloyd-Jones
Dr. Martyn Lloyd-Jones (1899-1981) was a Welsh evangelical minister who preached and taught in the Reformed tradition. His principal ministry was at Westminster Chapel, in central London, from 1939-1968, where he delivered multi-year expositions on books of the bible such as Romans, Ephesians and the Gospel of John. In addition to the MLJ Trust’s collection of 1,600 of these sermons in audio format, most of these great sermon series are available in book form (including a 14 volume collection of the Romans sermons), as are other series such as "Spiritual Depression", "Studies in the Sermon on the Mount" and "Great Biblical Doctrines". He is considered by many evangelical leaders today to be an authority on biblical truth and the sufficiency of Scripture.
