Book excerpt: In 1951, with the Second World War not long over and the menace of the Cold War generating anxiety in the West, Martyn Lloyd-Jones preached eight sermons on John 14:1-12 at Westminster Chapel in London. These sermons, presented in Let Not Your Heart Be Troubled, were intended to comfort, strengthen, and build up Christians in their "most holy faith" and to bring unbelievers to a knowledge of the only way men and women can face matters of life and death. Lloyd-Jones went through these verses carefully, showing that the way to deal with our fears is first to recognize and confront them and then to realize that the answer is only to be found in the great and unchanging truths of the gospel. Pastors, Lloyd-Jones readers, and anyone needing encouragement will benefit from this work by one of the twentieth century's foremost preachers.
