This song is pretty easy, the same progression covers the entire song.  
To play the mandolin part you can capo at the 12th and alternate pick 
between the third and first strings.

                           G                 D                  C 
It’s the same old story, I was young I was naive
                 G     D                       G
And I was dumb, my pops said stand
               D
But then I ran 
            C                      G     D  
Into the trap of Satan’s plan

Chorus:
             G                                 D
And the dog that spread those lies
       C                        G   D
And with those lies I ran 
                   G                          D
Just like the water reflects the face 
           C                         G    D
So the heart reflects the man 

I was a wreck doped up and drugged 
Against my chains I would have tugged 
But then He saved me called me his one
And to the Father I became a son

Chorus:
And the dog that spread those lies
And with those lies I ran 
Just like the water reflects the face 
So the heart reflects the man 

On that hill upon a tree hung a man who died for me 
As he hung there about to die I saw the water pour from his side 
He said "my son, your sins are vast 
But they are gone now, thrown to the past 
Walk with me now boy, through fields of green
In this pool of water your face I’ve seen"

Now it’s the same great story I was young I was naive and I was dumb 
But then He saved me, called me His one 
And to the Father I became a son

Chorus:
And the dog that spread those lies
And with those lies I ran 
Just like the water reflects the face 
So the heart reflects the man
