Sodom Had No Bible by Leonard Ravenhill and published by Ravenhill.
In this book which is a series of studies about revival, David Wilkerson writes "Leonard Ravenhill writes with the power and unction of John Wesley. It is impossible to read his works and still remain uncommitted."
When you read this book you are likely to come to the same conclusion. Here are twenty burning essays on the need for spiritual awakening and ten chapters on the impressive lives of remarkablely effective Christians who were leaders in true revival. Such an array of truth is bound to make a lasting impression on you.
