Capo 6 for original key.
The intro and Verse 1 are both played completely on G chord (for rhythm). 

VERSE 1:

G
Down in adoration falling
This great sacrament we hail
Over ancient forms departing
Newer rites of grace prevail
Faith for all defects supplying
Where the feeble senses fail

VERSE 2:

G             
To the everlasting Father
G/f# (or D/F#)
And the Son who reigns on high
Em
With the Spirit blest, proceeding
D
Forth from each eternally
C
Be salvation, honor, blessing
Am                D     G
Might and endless majesty


CHORUS:
                C                    D
Jesus, Lamb of God, saving love for all
                     C                       D
Lord of heaven and earth, Father's love for all
  Em  Bm  C
I bow to You
                D                    C
Jesus, Lamb of God, saving love for all
                     D                       
Lord of heav'n and earth, 
  Em  Bm  C           D             G
I bow to You, bow to You, I bow to You
(From here there is an interlude that is the same as 2nd Verse)
G   D/F#   Em    D     C      Am--

VERSE 3:
G              D/F#
Pour upon us, Lord of mercy
Em              D       C
Spirit of Thy selfless love
Em              Bm       
Make of us one true heart yearning
C             Em      D
For the glory of thy Son
G                Am
Jesus, fire of justice blazing
Em          C       D    G
Gladdening light forevermore

(Chorus 4x)
                         C                            D
Jesus, Lamb of God, saving love for all
                                  C                              D

                                 D                       
Lord of heav'n and earth, 
  Em  Bm  C           
I bow to You, 
                         D                           C
Jesus, Lamb of God, saving love for all

Lord of heav'n and earth,

I bow to You,
                         D                            Em
Jesus, Lamb of God, saving love for all
                               D                       
Lord of heav'n and earth, 
              G                  Am              Bm               Em     D          G
I bow to You, bow to You, bow to You,  bow to You, I bow to You!
