We have seen that the authority of darkness is the kingdom of Satan and that Satan himself is darkness. The kingdom of Satan is a system. Not everything inthis system is evil. On the contrary, many things are good, or at least are considered good by society. Satan uses various things, both good and evil, to systematize people and to keep them in his system.We may still be under the authority of darkness in our married life. When a brother is exchanging words with his wife, both he and his wife are in darkness. Because they are in darkness, they accuse and blame each other.
