Lou Engle is the visionary and co-founder of The Call solemn assemblies, a movement of prayer gathering young adults to pray and fast for breakthrough and revival. The Call began in Washington, D.C., in 2000 gathering over 400,000 people to pray and fast for the United States. Since 2000, The Call has gathered hundreds of thousands of people to pray both national and internationally. After a few years of dormancy, The Call was revived on 07.07.07 with over 70,000 people gathering for The Call Nashville. Lou Engle's heart passion is to call young adults into a lifestyle of radical prayer, fasting and holiness. In 2004, Lou planted the first Justice House of Prayer in Washington, D.C., to contend with the injustice of abortion and to pray for righteous leaders to be raised up in America. Since then, JHOP's have emerged in San Francisco, Boston, New York and San Diego.
