Charles Spurgeon 
The Sin of Unbelief [EPUB ebook] 

Charles Haddon Spurgeon (19 June 1834 – 31 January 1892) was a British Particular Baptist preacher who remains highly influential among Christians of different denominations, among whom he is still known as the ‘Prince of Preachers’.
Spurgeon was to 19th century England what D. L Moody was to America. Although Spurgeon never attended theological school, by the age of twenty-one he was the most popular preacher in London.

A strong figure in the Reformed Baptist tradition, defending the Church in agreement with the 1689 London Baptist Confession of Faith understanding, and opposing the liberal and pragmatic theological tendencies in the Church of his day, Spurgeon preached to around 10, 000, 000 people, often up to 10 times each week at different places. Spurgeon was the pastor of the congregation of the New Park Street Chapel (later the Metropolitan Tabernacle) in London for 38 years, despite the fact he was part of several controversies with the Baptist Union of Great Britain and later had to leave the denomination. In 1857, he started a charity organization called Spurgeon’s which now works globally, and he also founded Spurgeon’s College, which was named after him posthumously.

Spurgeon was a prolific author of many types of works, including sermons, an autobiography, commentaries, books on prayer, devotionals, magazines, poetry, hymns and more.
