The Importance of Revival in Center Church

Tim Keller is an ecclesial revivalist, which he uses in center church. He might be similar to other neo Calvinists, but also different from in some other ways as well. The project of theological synthesis that so many recognize and you highlight so often in the book is something that Keller was self conscious about from early. Do you think it's a derivative of his personality and gifting? It seems to be an intuitive response to his own personal makeup.
