Intro: if you want to play it, but it sounds nice with just the piano: 
D A G D

VERSE 1: 
D
The Calmer of the sea 
A
Here in this room with me  
G
So gently welcoming  
D                A
The weakest things in me  
D
You are the blood over  
A
The door of my heart  
G
What pain You spared me from  
D               A
How could I know it all?  

BRIDGE: 
Bm            G        D       A 
Oh wonderful love, You died for me  
Bm         G      D         A
The power of Your life is in me  

Refrão -------------

                   D             A
Father, let Your light shine down on me 
             Bm                 G
Father, let Your light shine down on me 
               D            A 
No matter what the day or night may bring 
              Bm            G    
Father, let Your light shine down on me

VERSE 2: 
D
Oh Jesus, You became 
A
what was my deepest shame  
G
That at Your very name  
D                    A
My calloused heart would change  
D
How could You, oh perfect One  
A
Love me, when I have done  
G
nothing that's worthy of  
D
My freedom You have won
