How can I keep from singing?!

There is an endless song
Echoes in my soul
I hear the music ring
And though the storms may come
I am holding on
To the rock I cling

How can I keep from singing Your praise?
How can I ever say enough?
How amazing is Your love!
How can I keep from shouting Your name?
I know I am loved by the King
And it makes my heart want to sing!

I will lift my eyes
In the darkest night
For I know my Savior lives

And I will walk with You
Knowing You'll see me through
And sing the songs You give

I can sing in the troubled times
Sing when I win
I can sing when I lose my step
And I fall down again

I can sing 'cause You pick me up
Sing 'cause You're there
I can sing 'cause You hear me, Lord
When I call to You in prayer

I can sing with my last breath
Sing for I know
That I'll sing with the angels
And the saints around the throne
