Every Christian has to be able to apply biblical principles to the age in which they are living. In this book, Martyn Lloyd-Jones speaks into his own times, enabling his hearers to interpret current events and situations from a Christian perspective. The middle decades of the twentieth century were an important time in the history of Evangelicalism - a history which will be better understood by reading these addresses. A knowledge of the past is vital to a right understanding of the present, and although, on the surface the world has changed much since these addresses were first prepared, it is testimony to the clear insight of Dr. Lloyd-Jones that much of the content remains as sharply focussed and as relevant today as it was then.
