In his introductory essay to this selection from the writing and preaching of C.H. Spurgeon, Helmut Thielicke expresses his surprise and delight at his discovery of the great Victorian preacher. He draws out those qualities which made Spurgeon one of the most influential ministers of his day, and explains what it was that attracted the university professor to the self-educated Baptist preacher. Primarily, they share a recognition of the urgency of their "We stand in need of the simply way in which Spurgeon dares to say that what really and ultimately counts is to save sinners." Warmth, immediacy and directness are the hallmarks of Spurgeon; qualities which Thielicke's own remarkable sermons share, but which he feels much modern preaching lacks. It is a convincing testament to Spurgeon's continuing vitality and relevance, that Thielicke, one of the great modern preachers, should "Sell all that you have ... and buy Spurgeon."
Originally written in German, this book is in reality mostly sections from Spurgeon's 'Lectures to My Students' selected to introduce 20th century German preachers to Spurgeon and his method (I hate to use that word) of preaching. In saying that, Thielicke opens the book with a terrific essay on Spurgeon's preaching which is exceptionally good, and is possibly more relevant now than ever, particularly among conservatives. Thielicke says Spurgeon's success lies in the fact that he focuses on the speaker holistically and not his mere methods (though his methods will change as he changes). Spurgeon is aiming at thoroughly and holistically Christian people, who use all tools available prudently and in a sanctified way. He points out that this most clearly manifests itself in Spurgeon's 'cheerfulness' (a happy disposition that is different and thus alluring to those without religion), and 'worldliness' (a lifestyle that is 'incarnational,' that is thoroughly immersed in the talk and ways of his era, for the purposes of knowing how to communicate clearly and compellingly). Spurgeon's preaching was healthy because he was healthy.
Firstly this is in reality a collection of Spurgeon's instruction on preaching followed by two sample sermons, and Thielicke merely wrote a long introduction. I've read some Christian material from outside our current era and usually find it terribly dated... God has move on (!) Actually we have moved on as God has brought fresh revelation, however Spurgeon is as fresh and current as you could ever ask for. Some of the style and structure of the world has naturally changed, but the instruction is easily transferable and relevant today.
