The document summarizes the history of spiritual awakenings and revivals in the United States through prayer movements. It describes three Great Awakenings that occurred through prayer: the First in the 1730s-40s led by Jonathan Edwards that addressed moral decline; the Second in the early 1800s that stemmed rationalism and infidelity on campuses and in society; and the Third in the 1850s as a business leaders' prayer movement. It also discusses the Azusa Street revival of 1906 and notes that throughout history, nations thrive for 200 years before declining without spiritual renewal through prayer.
