Capo 1

Intro
D2    D2/F#   D2/C   Gsus

Verse 1
D2                              D2/F#   
I drug his name through godless places
               D2/C D2       Gsus
And I?ve known shame that no child of his should know
D2                       D2/F#
I?ve seen pain on broken faces
           D2/C       D2         Gsus
Beyond all thought of hope I was just too far from home
Bm             D               Em             C
Still I always wondered when I closed my eyes

CHORUS
      D                      G
After all I?ve done Could he run to me?
         Em                     C
Would he kiss my face? Could he even look at me?
      D                         G
After where I?ve been should he take me back?
        Em                 C
I would understand I?ve disgraced him
    G            Bm            Em   C
But it would be amazing If he still calls me son

D2    D2/F#   D2/C   Gsus

Verse 2
D2                          D2/F#
With nothing left for me to bring him
          D2/C    D2          Gsus
I left my pride and turned my heart toward home
D2                     D2/F#
I saw my home on the horizon
           D2/C   D2         Gsus
And from a distance I saw my Father
Bm               D           Em          C
Watching for his own with forgiving eyes

Chorus

Bb                          F                                 C
One day as I breathe my last And I know my days on earth have ended
           G                 
When every hour is spent
A Bb                           F                  C
  I will close my eyes in amazement And I?ll hear angels  
           A               D
They?ll be singing Amazing Grace
              G                                     
Cause he will run to me 
            Em                   C
And he will kiss my face He will not let go of me 
      D                       G
After where I?ve been He will welcome me 
        Em                   C
I won?t understand How he?ll put his robe on me 
G           Bm                Em    C
It will be amazing That he?ll still call me son
G       D                   Em            C               D
Amazing grace how sweet the sound When he calls me son 
  G                                        Em                    C
I once was lost but now I?m found Cause he calls me, he calls me Son
         D     G     Em                   C
It?s so amazing               He calls me Son.
