To promote the Sept. 4 release of Steven Furtick's Greater: Dream Bigger. Start Smaller (Multnomah Books), the author and lead pastor of Elevation Church in Charlotte, N.C., and his congregation are hosting a live online Greater Day event at www.greaterbook.com and www.elevationnetwork.com.

The promotion includes a Greater Day Twitter campaign to donate backpacks to school children in need for every copy of the book sold on its release day. For each message sent via Twitter to #greaterbook confirming a copy of Greater was purchased from any retailer, a backpack with school supplies will be distributed or given through a network of partner churches and outreaches across the country.

From 9 a.m. to 9 p.m. EST today, online viewers of the Greater Day event can participate in the Twitter campaign and also hear from Furtick as he goes behind the scenes and describes his heart and vision for Greater.

The book draws on the biblical story of Elisha to empower readers to take a God-given dream from idea to reality. Greater is a follow up to his 2010 book on prayer, Sun Stand Still (Multnomah Books).
