The open-ended nature of the lyrics has led to many interpretations. Journalist Michael Campbell believed the lyrics send "a message of hope" and wish for a "world that is not divided by class, wealth, race, or any other arbitrary criterion". With regard to the place Bono was referring to in the song, he said, "I'm not sure, really, about that. I used to think it was Belfast..." Journalist Niall Stokes believes the title was influenced by Bono's and his wife Ali's visit to Ethiopia as volunteer aid-workers. Bono has expressed mixed opinions about the open-ended lyrics: "I can look at it now and recognize that song has one of the most banal couplets in the history of pop music. But it also contains some of the biggest ideas. In a curious way, that seems to work. If you get any way heavy about these things, you don't communicate. But if you're flip or throwaway about it, then you do. That's one of the paradoxes I've come to terms with."
