We had Rev Murray preach for us in Sheffield Evangelical Presbyterian Church last Lord's Day. What a blessing it was and do check out the website to listen to the sermons (www.sheffieldpres.org.uk).
However, a friend of mine told me today that he has heard that the latest book by Iain Murray on J. C. Ryle is apparently outstanding. I commend this book, though I have not read it yet and also check out other books authored by Murray on the Banner of Truth website.
Two books to note written by him are "Evangelicals Divided" and " The Forgotten Spurgeon".
