When it comes to developing leaders within the Christian community, few are as successful as Rev. Dr. McKenzie “Mac” Pier, founder and CEO of Movement Day’s parent organization, The New York Leadership Center (NYCLC). A visionary, strategic thinker and social networker, Mac delights in bringing movers and shakers together to transform their cities. We recommend his book The Power of a City at Prayer: What Happens When Churches Unite for Renewal. Take a read of the book summary below—and check it out on Amazon, too. 

Months before September 11, 2001, many Greater New York churches were uniting together in one of the largest urban prayer movements in the world. So when disaster struck on that late summer Tuesday morning, the churches and people were already in place to comfort, heal and pray for miracles.Mac Pier and Katie Sweeting, coordinators for Concerts of Prayer Greater New York, write about their experiences in The Power of a City at Prayer. They explain how to build an urban prayer ministry, and they share powerful examples of how such prayer movements have dramatically influenced neighborhoods, communities and cities around the world–including New York City before and after September 11, 2001.
