Today there is an intense longing for an outpouring of the Holy Spirit that will stun the Church and the world. John Peters shows us that, whilst revival is a 'sovereign, supernatural move of the Holy Spirit and a pouring out of His life and power', God has sovereignly chosen individual men and women to be His 'human agents' in His initiating of revival. Featuring biographies of 25 key revivalists and drawing out the outstanding qualities and characteristics of each, the book challenges us to learn from these revivalists, and inspires us to pray for revival.
