The song is called "Safety Dance" and I immediately thought about the rapture when I heard it the first time. There are a few important verses that link it to that event.
1. "We can act like we come from out of this world, leave the real one far behind"
2. "Because your friends don't dance and if they don't dance, then they're no friends of mine"
Obviously the "Safety Dance" would be all of us escaping the hour of trial that is coming upon the whole world.
Also brings to mind the verse: "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven." Matthew 18:3
