Evangelical religion has always been characterised by seasons of refreshing. G.J. Morgan gives us a vivid and colourful account of the history of Revivals showing how first the church and then society at large responded to a movement to God. What is Revival challenges us to prepare for Revival, to laugh at impossibilities, and pray that the power of God will be felt in every village, town and city. that people of every background and culture will be moved by the heavenly message.
