How Can I Keep from Singing

My life goes on in endless song Above earth's lamentation. I hear the real, though, far off hymn That hails the new creation What through the tempest loudly roars, I hear the truth, it liveth. What through the darkness round me close, Songs in the night it giveth. When tyrants tremble, sick with fear, And hear their death-knell ringing, When friends rejoice both far and near, How can I keep from singing? 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?
