David Martyn Lloyd-Jones (20 December 1899 – 1 March 1981) was a Welsh Congregationalist minister and medical doctor who was influential in the Calvinist wing of the British evangelical movement in the 20th century.

Attending a London grammar school between 1914 and 1917 and then St Bartholomew's Hospital as a medical student, in 1921 he started work as assistant to the Royal Physician, Sir Thomas Horder.

[2] After struggling for two years over what he sensed was a calling to preach, in 1927 Lloyd-Jones returned to Wales, having married Bethan Phillips (with whom he later had two children, Elizabeth and Ann), accepting an invitation to minister at a church in Aberavon (Port Talbot).

After a decade ministering in Aberavon, in 1939 he went back to London, where he had been appointed as associate pastor of Westminster Chapel, working alongside G. Campbell Morgan.

He disagreed with the broad church approach and encouraged evangelical Christians (particularly Anglicans) to leave their existing denominations.

"[3] This was interpreted as referring primarily to evangelicals within the Church of England, although there is disagreement over whether this was his intention as there were other denominations with liberal wings.

Although Stott was not scheduled to speak, he used his position as chairman of the meeting to oppose Lloyd-Jones publicly, stating that his opinion was against history and the example of the Bible.

[4] This open clash between the two elder statesmen of British evangelicalism was widely reported in the Christian press and caused considerable controversy.

[5] Yet the disagreement remained and the following year saw the first National Evangelical Anglican Congress, which was held at Keele University.

At this conference, largely due to Stott's influence, evangelical Anglicans committed themselves to full participation in the Church of England, rejecting the separationist approach proposed by Lloyd-Jones.

Although there is an ongoing debate as to the exact nature of Lloyd-Jones's views, they undoubtedly caused the two groupings to adopt diametrically opposed positions.

[citation needed] For the rest of his life, he concentrated on editing his sermons to be published, counselling other ministers, answering letters and attending conferences.

[citation needed] Despite spending most of his life living and ministering in England, Lloyd-Jones was proud of his roots in Wales.

He best expressed his concern for his home country through his support of the Evangelical Movement of Wales: he was a regular speaker at their conferences,[8] preaching in both English and Welsh.

[citation needed] Since his death, the movement has published various books, in English and Welsh, bringing together selections of his sermons and articles.

[citation needed] After a lifetime of work, he died peacefully in his sleep at Ealing on 1 March 1981, St David's Day.

[citation needed] Since his death, there have been various publications regarding Lloyd-Jones and his work, most popularly a biography in two volumes by Iain Murray.

[11][full citation needed]Lloyd-Jones seldom agreed to preach live on television – the exact number of occasions is not known, but it was most likely only once or twice.

"[12] In other words, he believed that the preacher should be free to follow the leading of the Holy Spirit concerning the length of time in which he is allowed to preach.

Once, while unfolding to his congregation the internal work of the Holy Spirit in the life of a Christian, Lloyd-Jones marvelled at his experience preaching.

[17] Shortly after his death, a charitable trust was established to continue Lloyd-Jones's ministry by making recordings of his sermons available.
