One of the twentieth century's greatest authorities on revival, Leonard Ravenhill gives a no-compromise call to the principles of biblical revival. The heart of his message to the church is in this volume. Appalled by the disparity between the New Testament church and the church today, his message is drastic, fearless, and often radical. As timely a call to revival today as when published nearly fifty years ago, more than 350,000 copies are in print worldwide. Includes questions for group and individual study.
