How Can I Keep from Singing Lyrics

How can I keep (how can I keep)
How can I keep from singingMy life flows on in endless song
Above the lamentation
I hear the sweet (I hear the sweet)
The far off hill (the far off hill)
That hails a new, a new creationThrough all the tumbled and the strife
I hear the music ringing
It finds an echo (echo)
In my soul (in my soul)
How can I keep from singingThe piece of Christ makes fresh my heart
A fountain ever springing
All things are mine since I am his
How can I keep from singingSince Christ is Lord (since Christ is Lord)
Of heaven and earth (of heaven and earth)How can I keep from singing
