The main point of this song is that Bob seems to be trying to highlight all the differences between what is happening inside the "gates of Eden" and what is occuring in the real world. So for me the song is saying religious people preach to you of paradise in the afterlife and try to tell you, you should follow their religion because of how great this life will be, whislt at the same time behaving in exactly the opposite way in the real world, as though this promise of paradise is a licence for their hypocrisy and the chance to fool people into believing their pointless lives are worthwile.
