Spiritual warfare is not a new topic, nor is it a human invention. It does not arise from academic theological thought, nor from exegetical doctrines.Satan, the prince of this century, is in constant war activity, and his purpose is to take captive the souls of generations born under the promise of restoration.Although it is most evident in the New Testament, the entire Bible bears witness to the reality of spiritual warfare. We find the evidence in all the books.In the book of Genesis, in the first Words of God addressed to Eve, after the judgment on disobedience has been carried out, they give clear testimony that the generation of the children of God will be in constant spiritual war against the generation of the serpent,In the remaining books of the Old Testament there are also compelling testimonies of spiritual warfare. The titles granted to the Almighty show that these are not just human wars, that behind what seem like regional rivalries, there are demonic forces intervening over which God himself executes the order of battle.• In the book of Exodus the name of Jehovah God appears as a man of war,• In the books of Samuel he appears for the first time calling God, Jehovah God of hosts,• In the books of Samuel the title also appears, the wars of Jehovah,What is the point of God himself using names of war, if spiritual warfare does not exist?
