I love the simplicity of the meaning and purpose of this song, along with how they played, matching the strength, overbearing power and intensity of the lyrics. I'm not one to be religious, but just having the sense of perspective from a religious point of view, and understanding the relationship between the demon and what will happen if you are not saved by a saviour, is powerful, because this can be applied to just about any situation with a great evil and has the ability to get to a safe haven. The serpent rising from depths refers to Satan uprising from hell, One key is the use of the word serpent in identifying this being as Satan, which serpent is as in a snake, which is the creature Satan posed as in the garden of Eden with Adam and Eve. The declining of the world is how it travels, descending into hell, whereas decaying of the world refers to the transformation into hell.
