Reign of love
I can't let go
To the sea I offer
This heavy load
Locusts will lift me up
I'm just a prisoner
In a Reign of love [ Lyrics from: http://www.lyricsmode.com/lyrics/c/coldplay/reign_of_love.html ]
Locusts will
Let us stop
I wish I'd spoken
To the Reign of love
Reign of love
By the church we're waiting
Reign of love
My knees go praying
How I wish I'd spoken up
Or we'd been carried
To the Reign of love
This song always makes me feel of my ex who died a few years ago. In my opinion reign of love refers to god to whom he wishes he had spoken in his life, then the song says by the church were waiting as his knees go praying. It' as if he's waiting for the day of judgement.
