Flood

If I can summarize this shortly, it is simply about recognizing yourself in a new perception. Biblical references or not, the song speaks of becoming aware or 'waking up' to the reality around you. It is about seeing reality for what it is beyond your expectations and beliefs. This happens through life experience. When you experience something you believe it, and you can hear someone preach something all day, but you may not actually change your mind about something until you have a new experience.

The person in this song is seeing reality in a way he never saw before because he put barriers on his perception, maybe believing his actions were caused by fate or some outside force rather than himself, but he wakes up to the reality of free will, and all his decisions were made by him, not the outside force, and that his freedom and deliverance was the free will he has had all his life. The past beliefs are just images, siguls, ideas. They are not reality what he sees now. The flood represents his new understanding of things, and how this new perception will 'flood' his consciousness and his life experience will exist through new understanding. The flood of this new perception will cleanse the mind, since this understanding of reality can no longer be repressed by fallacies or lies or false perceptions; it is inevitable. The old ideas will be purged, and the new perception will cleanse his consciousness and purge the false perceptions. In short, the song is about awakening to reality and the experience of it.
