Well, Bono's lyrics often carry double meanings, don't they?Ain't that the truth.
You have to also consider the line right before it as well:
"If you want to kiss the sky"
I always took that as 'getting to Heaven'.
absolutely! but depends what you would define heaven as
I didn't really finish my thought there...
To me, it's someone making a threat about getting to Heaven - If you wanna kiss the sky better learn how to kneel.
Then it moves to a demand - On your knees boy!
Double meaning? Definitely.
He seems to get back to this when he writes - Blessings are not just for the ones who kneel. Luckily.
