David Martyn Lloyd-Jones (20 December 1899 – 1 March 1981) was a Welsh Protestant minister, preacher and medical doctor who was influential in the Reformed wing of the British evangelical movement in the 20th century. For almost 30 years, he was the minister of Westminster Chapel in London. Lloyd-Jones was strongly opposed to Liberal Christianity, which had become a part of many Christian denominations; he regarded it as aberrant.
Charles Haddon (CH) Spurgeon (19 June 1834 – 31 January 1892) was a British Particular Baptist preacher. Spurgeon remains highly influential among Christians of various denominations, among whom he is known as the "Prince of Preachers". He was a strong figure in the Reformed Baptist tradition. Spurgeon produced powerful sermons of penetrating thought and precise exposition. Many Christians have discovered Spurgeon's messages to be among the best in Christian literature.
