Who but Thou, almighty Spirit, Can the heathen world reclaim? Men may preach, but till Thou favor, Heathens will be still the same: Mighty Spirit, Witness to the Savior’s name. Thou hast promised by the prophets, Glorious light in latter days; Come and bless bewildered nations, Change our prayers and tears to praise: Promised Spirit, Round the world diffuse Thy rays. All our hopes, and prayers, and labors, Must be vain without Thine aid: But Thou will not disappoint us; All is true that Thou hast said: Gracious Spirit, O’er the world Thine influence spread.
