When Martyn Lloyd-Jones, physician, preacher and Christian Leader, died in 1981, after more then 40 years in London, few knew the remarkable story of his formative earlier years which, in the authorised biography, is now told for the first time. From his rural Welsh background to St Bartholomew's Hospital (where at the age of 23 he was Chief Clinical Assistant to Sir Thomas Horder, the King's Physician), then, suddenly at 27, to a struggling Calvinistic Methodist Church in Aberavon, South Wales, he appears successively as schoolboy, dairyman's assistant, political enthusiast, debater, doctor, and finally Christian preacher. Some regarded his change of career as romantic, others as foolish. The one thing of which Dr Lloyd-Jones was sure was that his settlement amid the industrial depression of South Wales was no sacrifice: 'I gave up nothing. I received everything. I count it the highest honour God can confer on any man to call to be herald of the gospel'.
