There is a great war being waged in the world today. It is not a conflict between nations, tribes, or government leaders. It is not a rebellion or coup. It is an important invisible battle taking place in the spirit world. The Bible states that God's people are destroyed because of lack of knowledge (Hosea 4:6). One of the main areas in which believers are being defeated due to lack of knowledge is in spiritual warfare. The early Church viewed their spiritual experience in terms of warfare. Military terminology is used throughout the New Testament. Protection was seen in the armor of God and the Word of God was compared to a sword. Satan's attacks were called fiery darts. Faith was the "good fight" and believers were told to "war a good warfare." The early Church knew they were engaged in an intense spiritual struggle. The same spiritual battle continues today but instead of fighting the enemy, believers are often building great church buildings, producing musical dramas, holding fellowship meetings, and fighting one another while this great spiritual battle wages around them. Satan has even intensified his attacks against the church that has withdrawn from the front lines of battle. As the end of time approaches it is even more important for believers to understand spiritual warfare than in the early days of church history. The Apostle Paul warned: "This know also, that in the last days perilous times shall come." (II Timothy 3:1) In order to be properly prepared for these perilous times, renewed emphasis must be placed on the strategies of spiritual warfare. The Christian life is war. The sooner we recognize and prepare for it, the sooner we will experience victory. Luke 14:31 says, "What king, going to make war against another king, sitteth not down first, and consulteth whether he is able with ten thousand to meet him that cometh against him with twenty thousand?" No king ever entered into a battle without a careful examination of his resources and development of battle strategies. In essence, that is what we are doing in this course. We are making a careful evaluation of the strategy, weapons, and power available to us to win the war against our enemy, Satan. In the military world, "strategy" is the science of forming and carrying out military operations. It is the method or plan which leads to the goal of victory. In this book you will learn to formulate and carry out spiritual military strategy which will bring victory in the spirit world.
