I used CowManJones' version and added and changed some Chords.
It should sound quite good, although I can't guarantee for accuracy.
The G-D-Em-part in the verse could also be C-D-Em
The original song seems to be played like this (with Em,D,G,C and so on) but in 
Half-Step-Down-Tuning  
Have fun :)

Em                                               D
All my life, I've waited and watched through the eyes of faith
   Em                     G D Em
To see the consolation of Israel
Em                                          D
And even though the flame of my life is now growing dim
  Em                          G D Em
I know I'll see the Savior of Israel
        G                      D
For the Spirit of the Lord has promised unto me
     G                               G         D    Em
That I would not see death before my eyes have seen Him
    G                     D
The promise is alive, for through this little child
      G                        G D Em
God's holy light illuminates Jerusalem
