The concept of Leviathan has spawned an immense number of legends, in the church as well as on the dark side. We spent over a dozen years sifting through the mass of perceptions out there, trying to find actual information!
In the end, as usual, the Bible interprets itself. We found that the seven heads of Leviathan are correlated to the seven principles. As we master each of the seven principles, it will give us authority over that specific head.
So this is not an issue of deliverance per se, although there is room for that. There is a lifestyle cause to having one or more of the seven negative heads operant in your life, and there is a lifestyle change that will bring about the power of the positive heads.
The seven heads of Leviathan deal with nature and they are, in order: light, weather, life, time, sound, motion and essence.
The most familiar head is the fifth head which deals with sound and all its ramifications in communications. There are people who are rarely misunderstood. There are others who live in a world of misunderstanding.
There are those who have a fairly normal relationship with their electronic equipment. There are others whose equipment breaks down with monotonous regularity.
These are fruit issues related to the negative or positive heads of Leviathan.
At the end of the day, God did not design us to be powerless. Powerlessness and oppression rob us of our joy. When we are walking in dominion over these areas, there is deep, pervasive joy.
