12Therefore sin is not to reign in your mortal body so that you obey its lusts, 13and do not go on presenting the parts of your body to sin as instruments of unrighteousness; but present yourselves to God as those who are alive from the dead, and your body’s parts as instruments of righteousness for God. 14For sin shall not be master over you, for you are not under the Law but under grace.
12Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof. 13Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God. 14For sin shall not have dominion over you: for ye are not under the law, but under grace.
Let not sin therefore reign in the mortal body. Doctrine is always something to be applied, not just considered. In this sermon on Romans 6:12–14 titled “Let Not Sin Reign,” Dr. Martyn Lloyd-Jones divides Christians into two groups based on interest in doctrine verses practical matters. Is Christian doctrine simply an intellectual hobby? What is the distinction between a person and their “mortal body”? Look at the connection between mortality and corruption. Sin remains in the body and if it is not kept in check, then it will reign in the body. Sin is not dead, but the Christian must remain dead to sin. The Christian is encouraged to yield the body as a slave to righteousness and holiness and not allow sin to reign, for God provides a way out. Listen as Dr. Lloyd-Jones give the exhortation that the Christian is called not to a sudden deliverance but to a life of sanctification. For the Christian who longs to be holy, they must understand this doctrine and continually remind themselves of it. It is the truth that sanctifies and makes one free. “It is God’s purpose to make us holy and He is working in us,” Dr. Lloyd-Jones reminds the listener. Resist the devil and he will indeed flee.
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.
