Will we light the spark?

Reading up on the Third Great Awakening (1850-1900) for a history paper.  Many profound things marked this revival, both positive and negative, but the emphasis on prayer and unity really struck me.  Walter Hampel writes, "Denominational differences were considered important but secondary to the purpose of seeking God’s face in prayer."  This unity in prayer is credited with much of how the revival "spread to be like a lightning strike in a forest".  Christians, will we light the spark of revival on our knees?
