Okay, so this is my first one. But i think it turned out pretty good! :)
I have played it along the song, and most of it is rigt! 

Intro: E, a few times.

Verse:
E                                B
I see your face, I look in your eyes
                       A
What you feel is no surprise
                               E
Everyone needs somethin\' to believe in

E                                   B
Tell me your dreams I'll tell you mine
                             A
In our hearts we'll look inside
                                 E
and see all the colors of the rainbow
I know

Chorus :
E                             
We all want to believe in love
B                                 A
We all want to believe in something
                  B
Bigger than just us

E
We all want to be a part
B                    A
Of the greater picture
A                        B 
That's hanging in our hearts (our hearts)
B           A          B
Yeah, it's bigger than us

Verse:
E                                   B
I want to see beyond my own little world
                           A
Grab your hand so we can twirl around the galaxy
                     A
See the world with clarity oh, oh
    E                              B
Oh, oh, we have such a long way to go
       A
But I know
                             E
We\'re getting closer every day
EVERY DAY!

Chorus :
E                             
We all want to believe in love
B                                 A
We all want to believe in something
                  B
Bigger than just us

E
We all want to be a part
B                    A
Of the greater picture
A                        B
That's hanging in our hearts (our hearts)
B           A          B
Yeah, it's bigger than us

    A
It fills the universe, 
    B
It lights the skies above,
     A                       E
And rescues our hearts with love, 


L-O-V-E 

Love
 B
We love 

L-O-V-E 
 
Love  A
                B         E
That's what's bigger than us! (bigger than us!) 


(I don't really know how this part goes, but something like the other ;) )


(C'mon!) 
It's love, It's love 
That's bigger than us, 

(C'mon!) 
It's love, It's love, 
That's bigger than us 
(Whew!) 
It's love, It's love! (it's love, it's love!) 

E                    
We all want to believe in love, 
B
We all want to believe in something, 
A                  B
Bigger than just us!
