Peace: An idealistic but laudable goal

About 40 years ago, "Let There Be Peace On Earth" was one of my favorite hymns to sing in church.  I liked the song's goal of a peaceful planet, with everyone doing their part.  Although I don't dislike the hymn now, I look back and think, "It's easier to be peaceful when you don't have to have a job, pay bills, or have any major health issues.  The lyrics still appeal to the idealist in me, though, so no wonder that my nine-year-old self liked it."
