Soulfully. Nice and slow. If you're in a band this song works well with the drummer starting a building celtic rhythm on his toms in the second verse and exploding into the last- in this case distortion and powerchord the last verse!

E                          F#m E/G# A
How deep the Father’s love for us 
     E                 C#m  B7
How vast beyond all measure
     E                   F#m E/G# A
That he should give his only Son
       E/B                      B7    E
To make a wretch his treasure
     E/G#                  A/C# E/B A
How great the pain of searing loss
        E/G#                  C#m  B7
The Father turns his face away
       E                F#m  E/G#  A
As wounds which mar the chosen one
       E/B                  B7   E   F#m E/G#  A2   E/B B7 E
Bring many sons to glory 

Behold the man upon a cross
My sin upon his shoulders
Ashamed I hear my mocking voice
Call out among the scoffers
It was my sin that held him there
Until it was accomplished
His dying breath has brought me life 
I know that it is finished

I will not boast in anything 
No gifts, no powers, no wisdom 
But I will boast in Jesus Christ 
His death and resurrection
Why should I gain from his reward?
I cannot give an answer
But this I know with all my heart
His wounds have paid my ransom
