The chords are very easy. It just goes C F C G. 

C                              F 
Baby, let your light shine on me 
                     C 
When I'm lost on the road 
                          G 
You know you could set me free 
                  C 
You could ease my load 
 C           F                       C 
Days get so dark that I can't hardly see 
C                 G                           C 
I've been gone so long, it seems like home to me 

Baby, when I was young of age, I took you for my world 
The oceans were your eyes, the pastors were your curves 
But now I'm all alone stranded in the West 
Where you sleep tonight I can only guess 

Baby, let your light shine on me 
When I'm lost on the road 
You know you could set me free 
You could ease my load 
There's something on the hills you know I gotta see 
I've been gone so long, it seems like home to me 

Well, baby, I gave you all I got and told you all I know 
But you want someone I'm not so it's time for me to go 
When a sparrow needs its rest, it takes the nearest tree 
But if I pass back this way, there's still light on me 

Baby, let your light shine on me 
When I'm lost on the road 
You know you could set me free 
You could ease my load 
There's something that I lack, it just won't let me be 
I've been gone so long, it seems like home to me 

Baby, let your light shine on me 
When I'm lost on the road 
You know, you could set me free 
You could ease my load 
I guess I'll just keep on until I reach the sea 
I've been gone so long, it seems like home to me 
It seems like home to me 
It seems like home to me
