How Can I Keep from Singing

My life goes on in endless song
Above earth's lamentations
I hear the trumpets sounding strong
That hails a new creation
Through all the tumult and the strife
I hear it's music ringing
It ever echoes in my life
How can I keep from singing?
And though the shadows gather round
The endless song it giveth
My strength within and joy unbound
The world of truth it liveth
Though dark the night and long the road
I hear the music ringing
And with such power and grace bestowed
How can I keep from singing?
No storm can shake my inmost calm
While to this rock I'm clinging
How can I ever come to harm?
How can I keep from singing?
Then sings my soul with love profound
A fountain ever springing
Deep from the earth, how sweet the sound
How can I keep from singing?
