'Kathryn Kuhlman spoke on the power of the Holy Spirit from the pulpit and on the radio. The Greatest Power in the World records many of her inspiring messages. No woman in the 20th century demonstrated the restoring and healing power of the Holy Spirit to more people than Kathryn Kuhlman. She offered hope and courage to Christians struggling with spiritual, emotional, and physical obstacles, and pointed them unerringly to the source of power they needed to live victoriously: the Holy Spirit.'
