Lyric discussion by Anne Marie 

In the Rolling Stone interview Bono says that this song is about agape love. The Greek apparantly have three words for love: agape love is unconditional love, like the love for God. There was also erotic love and friendly love (can't remember the exact words for those ones). The interviewer then asked Bono if this song was about his mother and he agreed, but said that it could also be about God.
