The Cyber Hymnal link, above, gave an older version of the song. Does anyone know where / when this verse came in?
What though the tempest loudly roars
I hear the truth -- it liveth!
What though the darkness 'round me close,
Sounds (or ?songs?) in the night, it giveth. No storm can shake my inmost calm
While to that rock, I'm clinging.
Since Love is Lord of Heaven and Earth
How can I keep from singing?
The substitution of "love" for "Jesus" or "Savior" would suggest that it's modern. Did Doris Plenn pen this as well?
