There has been many revivals that occurred on earth including the days of Jonah 2----3. The days of the prophet Elijah and Ahab. 1 kings 18:17---46. The days of the early church.Act 2:1---end. The people also experienced the Wales revival, the Azuza street revival, the Brownsville revival, and most recently the Toronto Airport Christian fellowship revivals.
