O for a glance of heavenly day, To take this stubborn heart away, And thaw, with beams of love divine, This heart, this frozen heart of mine. The rocks can rend; the earth can quake; The seas can roar; the mountains shake: Of feeling, all things show some sign, But this unfeeling heart of mine. To hear the sorrows Thou hast felt, O Lord, an adamant would melt: But I can read each moving line, And nothing moves this heart of mine. Thy judgments, too, which devils fear? Amazing thought! unmoved I hear; Goodness and wrath in vain combine To stir this stupid heart of mine. But something yet can do the deed; And that dear something much I need: Thy Spirit can from dross refine, And move and melt this heart of mine.
