And to comment as to the content of the lyrics for this particular song, I think it is talking about the Biblical reference in Proverbs about resolving conflict before the sun goes down. What comes to mind first when I hear this song is I imagine a husband and wife that have been having this longstanding unresolved conflict, and then after putting it off, before they know it it's too late to fix it - maybe one of them wants a divorce, or perhaps one of them dies. And the one remaining is left with regret that they didn't try to make things right when they still had the chance. I suppose it could also apply to other family, boyfriend/girlfriend, or just regular friendship.
