Rowland Hill - The Second Whitefield by Tim Shenton and published by Day One Publications.
Lady Huntingdon at the time of his preaching wrote "The crowds that follow Rowland Hill wherever he is called to preach, overwhelm me with astonishment, and gratitude to the God of all grace, who has endowed him with such gifts. He boldly proclaims the doctrines of the cross, and the word of the Lord runs and is glorified in the conversions of multitudes.
A hundred awakened souls, the fruits of his preaching, have been received into the Tabernacle Society. I have attended him at Blackheath and Kennington, where the Lord blessed his testimony in a very remarkable manner. Thousands and thousands attended, and the most awful and solemn impressions seemed to pervade the vast assemblies.
Excepting my beloved and lamented Mr Whitefield, I never witnessed any person’s preaching wherein there were such displays of the Divine power and glory. May HE who has raised up this second Whitefield, with talents and zeal so distinguished, make him eminent in his day and generation, and crown his message with success."
