For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places. Ephesians 6.12.
Many people know only the battle between the spirit and the flesh; they do not perceive the conflict that rages between us believers and the evil spirits as described in the sixth chapter of Ephesians. The real spiritual battle is fought between us and Satan with his evil spirits. This battle is joined by all matured believers, for the children of God on earth are frequently attacked by evil spirits. Such attacks sometimes occur in the believers’ environment, sometimes in their physical bodies, sometimes in their thoughts, sometimes in their emotions, and sometimes in their spirits.
Too often believers are not aware of being attacked by evil spirits. They do not understand why everything seems to be against them, creating terrible confusion and trouble. They too often take these things as natural, not realizing that frequently they are being supernaturally oppressed by the evil spirits.
