I was prompted to include this song by the Easter Bible readings about the resurrection, in particular Mark 16:1-8. The women visiting Jesus’ grave in the hope of tending to his body are asking themselves ‘Who will roll away the stone from the entrance for us?’
You can’t get too analytical about the lyrics; on a plain reading they seem to be about some kind of relationship blockage – the ‘stone’. So I just go with the swell of emotion in the anthem style of the music and think about those few minutes as the women approached a grave, and met an angel. Maybe they sang about it for the rest of their lives.
