Lyric discussion by alkalinefan 

This song is about having a beautiful relationship with somebody, putting all your energy into it and convincing yourself that it completes you, only to realise after time that you're still searching for something more. In Bono's case he might be referring to religion but the perfect thing about this song is that it can apply to anything. We've all been there, we've all had relationships where we convince ourselves that we've found everything in this person. Over time though, as the dust settles we realise that while we still love them, there is still something more to life. While you can find happiness in other people, you'll never feel complete if you're not doing what you love.
