Now what does this mean? I know that we are all, according to the Bible, Abraham's sons and daughters, but it will always have that connotation of Isaac. It means either a. sacrifice all your sons because it is the will of God or else it means b. don't sacrifice all your sons even if it is the will of God. Now this is in contradiction with what U2 is supposedly all about. They preach about being so holy and following God and everything, yet they also preach for peace. So no matter how you look at this lyric (and I'm always going to see 'lay down' in the way it is used towards killing animals) it goes against their supposed beliefs, meaning they don't really think about what they say they just say it cause it sounds cool.
