The principle of authority is that we are in the kingdom of Christ. Jesus is Lord and head of all power and author-ity. Satan has legitimate absolutely no authority over the believer. We are free from Satan's claims upon us. One must never compromise this princi-ple by saying that sin gives a demon right to invade a believer or attach itself to your soul.
Light expels dark-ness.
The only spiritual information to be trusted is from God Himself. This comes through the Bible interpreted naturally. All other knowledge, information, experience is guilty until proven inno-cent and suspect even then. If it comes from demons, it is always pre-sumed a lie or facts given for dark purposes. Basic patterns of ministry are found in the Bible.
