Book excerpt: Many Christians who want to impact the world mistakenly assume that influence belongs only to the ministry front-man-not to the next tier of leaders and unseen servants. But the life of T. W. Wilson proves otherwise. As Billy Graham's closest friend and longtime personal assistant, T. W. Wilson turned his own valuable leadership skills to the task of supporting Billy and ended up influencing thousands of lives both directly and indirectly. His life is an inspiring testimony to the power of "next-level" servanthood to maximize the power of the church for the twenty-first century. Filled with interviews and stories from many of Billy Graham's associates and eight pages of photographs, this book offers a fascinating look inside the most successful evangelistic ministry of modern times as well as an inspiring blueprint for purposeful servant-leadership.
