The invisible spiritual war is a battle which involves all men and women. Because the Kingdom of Satan is a spiritual kingdom…
…we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (Ephesians 6:12)

Spiritual warfare is not a natural battle between flesh and blood. It is not a battle of man against man. It is not a visible battle. It is an invisible struggle in the spirit world. It is a battle within and around man. It is not a visible war because spirits are involved and we learn in Luke 24:39 that a spirit does not have flesh and bones.
When a nation declares war, they often issue “Articles Of War.” This document explains why they are at war, identifies the enemy, and declares the objectives of the war. The Bible is the written Word of the one true God, the Commander of our spiritual army. The Bible contains our “Articles Of War” for spiritual combat.
