Rejoice lyrics

It's falling it's falling
And outside the buildings
Are tumbling down
And inside a child on the ground
Says he'd do it again

And what am I to do
What in the world am I to say
There's nothing else to do
He says he'll change the world someday
I rejoice
[ Lyrics from: http://www.lyricsmode.com/lyrics/u/u2/rejoice.html ]
This morning I fell out of bed
When I woke up to what he has said
Everything's crazy
But I'm too lazy to lie

And what am I to do
Just tell me what am I supposed to say
I can't change the world
But I can change the world in me
If I rejoice
Rejoice...

And what am I to do
Just tell me what am I supposed to say
I can't change the world
But I can change the world in me
If I rejoice

I don't know what to change
Rejoice...
