How Can I Keep From Singing Lyrics

My life flows on in endless song
Above earth's lamentations,
I hear the real, though far-off hymn
That hails a new creation.

Through all the tumult and the strife
I hear it's music ringing,
It sounds an echo in my soul.
How can I keep from singing?

While though the tempest loudly roars,
I hear the truth, it liveth.
And though the darkness 'round me close,
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?

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?

In prison cell and dungeon vile
Our thoughts to them are winging,
When friends by shame are undefiled
How can I keep from singing?
