Well, it goes like: Dm - Am - C - G all over the song.

Intro - Dm - Am - C - G 
While singinh this part: 
Open up ya eyes and watch the sunrise
One part of me I?ve been made clear
Love that goes spread all the world, you know

And then:

Dm                      Am
My love ya comes out of devotion
   C                  G
To rule ya spread to the world
   Dm                   Am
In Trenchtown I?m on my mission
         C                 
Where we praise the day straight our way
        G
All the nation
              Dm
Let me be the love that comes form the sun
               Am
Let me be your rainbow rising on
       C
Every single race out of space
     G
Will Shine on, shine on!



And so on.
Hope it's correct and you like it.
