Amidst the corruption and moral decline of 1857 America, Jeremiah Lamphier initiated a powerful revival in New York City through a noonday prayer meeting that rapidly grew to over 10,000 participants. This movement, known as The Prayer Meeting Revival, fostered unity among churches and spread across the U.S. and Great Britain, resulting in over a million new church converts in just two years. Key figures like William and Catherine Booth, Charles Spurgeon, and D. L. Moody emerged from this transformative period, which highlighted the profound impact of prayer on individual lives and society as a whole.
