A revival is a miracle. It is a miraculous, exceptional phenomenon. It is the hand of the Lord, and it is mighty. A revival, in other words, is something that can only be explained as the direct action and intervention of God. It was God alone who could divide the Red Sea. It was God alone who could divide the waters of the river of Jordan. These were miracles. Hence the reminder of God’s unique action of the mighty acts of God. And revivals belong to that category. . . . These events belong to the order of things that men cannot produce. Men can produce evangelistic campaigns, but they cannot and never have produced a revival. (Martyn Lloyd-Jones, Revival, 1987)
