Why should I be lonely, long for heaven and home 
When Jesus is my portion and a constant Friend I know 

I sing because I'm happy, I sing because I'm free 
For His eye is on the sparrow, His eye is on the sparrow 
And I know He's watching me 

Why should I be troubled when His tender word I hear 
 I rest on His goodness in my doubt and in my fear
 
I sing because He loves me, I sing because I'm free 
For His eye is on the sparrow, His eye is on the sparrow 
And I know He's watching me
