How can I keep from singing?

A friend recently called my attention to this hymn. It was unfamiliar to me although far from new. It's a 19^th century hymn by Robert Lowry who also wrote, among others, "Shall We Gather at the River?" "I Need Thee Every Hour," "All the Way My Saviour Leads Me," and "We're Marching to Zion."

How Can I Keep From Singing?

My life flows on in endless song, above earth’s lamentation. I catch the sweet, though far-off hymn that hails a new creation.	What though my joys and comforts die, I know my Savior liveth. What though the darkness gather round? Songs in the night he giveth. [Refrain]
Refrain: No storm can shake my inmost calm      while to that Rock I’m clinging. Since Love is lord of heav’n and earth, how can I keep from singing?	The peace of Christ makes fresh my heart, a fountain ever springing! All things are mine since I am his! How can I keep from singing? [Refrain]
Through all the tumult and the strife, I hear that music ringing. It finds an echo in my soul. How can I keep from singing? [Refrain]	Robert Lowry (1826-1899)
