The Lower Lights lyrics

Brightly beams our father's mercy From his lighthouse evermore But to us he gives the keeping Of the lights along the shore Let the lower lights be burning Send a gleam across the wave Some poor, fainting, struggling seaman You may rescue, you may save Dark the night of sin has settled Loud the angry billows roar Eager eyes are watching, longing For the lights along the shore Trim your feeble lamp, my brother Some poor sailor tempest tossed Trying now to make the harbour In the darkness may be lost
