This book traces the main lines of Spurgeon’s spiritual thought in connection with the three great controversies in his ministry- the first was his stand against the diluted gospel fashionable in the London to which the young preacher came in the 1850’s; the second, the famous ‘Baptismal Regeneration’ debate of 1864; lastly, the lacerating Down-Grade controversy of 1887-1891 when Spurgeon sought to awaken Christians to the danger of the Church ‘being buried beneath the boiling mud-showers of modern heresy’.
