Few who heard Dr Martyn Lloyd-Jones preach will ever forget the experience, not because of his presence as a minister, but on account of the sense of wonder at the gospel that he conveyed. Those, like the author, who had the privilege of knowing him up close, are uniquely placed to comment on his life and passion. Christopher Catherwood examines the remarkable legacy of his Welsh grandfather, tracing his relevance to the twenty-first century. Dr Martyn Lloyd-Jones was adamant that all doctrine and practice should originate in Scripture. This volume focuses on key principles, showing how these were arrived at using a biblical framework. The author looks at the controversies, but sets them in context. This is not a conventional biography, but one that sheds light on a hugely interesting era of UK evangelicalism, which we do well to remember.
