Norman Vincent Peale begins by expressing his deep gratitude for the success of his book on the occasion of its two-millionth copy. However, he emphasizes that his joy comes not from the number of copies sold, but from knowing that his teachings have helped many people live better and more peaceful lives.

He explains that the principles of positive thinking and faith in the book were discovered through his own struggles and personal experiences. Peale credits the teachings of Jesus Christ as the foundation of his philosophy and states that he merely translated those eternal truths into modern, understandable language.

Before writing, Peale and his wife prayed sincerely for God’s guidance, dedicating the book to help ordinary people find peace, strength, and victory in their daily lives. The book, he notes, is written especially for common people—those who face pain, difficulty, and struggle—but who can overcome challenges through faith and positive thinking.

Peale clarifies that positive thinking is not a path to fame or wealth, but rather a spiritual discipline—a practical application of faith that brings inner peace, creative energy, and joy. He concludes by expressing appreciation to his readers and publishers, and he prays that the book will continue to be a source of spiritual strength and human helpfulness
