Arnold Dallimore has written an excellent biography on the nineteenth century baptist preacher. He has obviously researched his subject well, and the book begins with an interesting description of life in nineteenth century England and the circumstances that Spurgeon was born into.
We are told of Spurgeon's upbringing and his conversion in the small methodist church in Colchester. As his ministry begins and progresses, we get insights into the making of Spurgeon and some of his achievements. We can also get an idea of his preaching at the Metropolitan Tabernacle at London, and the effect it had on so many.
Spurgeon's struggles in later life, both with health and the 'Down-Grade Contreversy' are also looked at. The book then ends with an interesting appendix detailing the history of the Metropolitan Tabernacle after Spurgeon's death. This would make an interesting study on its own!
It's an excellent biography, which is much more condensed than the two-volume autobiography, and yet still so full of information. As you read, you will long, that God would do in the present day, what he did then, and that more preachers like Spurgeon would be raised up. If you only want to read one book about Spurgeon, then I would certainly suggest this one. However, if you want a bit more, get Iain Murray's excellent 'The Forgotten Spurgeon.'
