Revival, as contrasted with a Holy Ghost atmosphere is a clean- cut breakthrough of the Spirit, a sweep of Holy Ghost power, bending the hearts of hardened sinners as the wheat before the wind, breaking up the fountains of the great deep, sweeping the whole range of the emotions, as the master hand moves across the harp strings, from the tears and cries of the penitent to the holy laughter and triumphant joy of the cleansed.
