Rick Warren is often called "America's most influential spiritual leader." He and his wife, Kay, founded Saddleback Church in Orange County, California, which is now one of the largest and best-known churches in the world. He also wrote the #1 all-time bestselling hardcover book, The Purpose Driven Life. Pastor Rick has spoken in 165 nations, as well as at the United Nations, US Congress, numerous parliaments, the World Economic Forum, TED, and the Aspen Institute, and lectured at universities including Oxford, Cambridge, and Harvard. Pastor Rick's current passion is found in his role as Executive Director of the Finishing the Task Coalition--a call of thousands of believers, churches, denominations, and organizations coming together to fulfill the Great Commission by 2033, the 2000th anniversary of the call by Jesus to "go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.".
