For half a century, Norman Vincent Peale was one of the most influential clergymen in the United States. Brilliantly combining the wisdom of Christianity with a deep understanding of human psychology, Peale delivered a message about the power of faith that resonated with people of all denominations. The most famous of his forty-six books, The Power of Positive Thinking, has remained in print for fifty years, sold fifteen million copies, and been translated into forty languages. Peales legacy continues today through the work of the Peale Center for Christian Living, the Outreach Division of Guideposts, which is still run by members of his family, and the magazine Guideposts, which has a circulation of more than 3.2 million.
