1 Peter 5:8-9 Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. (9) Resist him, steadfast in the faith, knowing that the same sufferings are experienced by your brotherhood in the world.
All unbelievers are in Satan’s kingdom, and he holds sway over all of them to a greater or lesser degree, and so none of them pose any threat to his reign in the earth. But there is a group of people in the earth today, over which he holds no sway, because they are not in his kingdom, and that is the church of our Lord Jesus Christ. It is precisely because believers are not subject to the devil, that they are the greatest threat to his reign in the earth. And so, Satan does everything in his power to destroy the church of our Lord Jesus in the earth, which is why the above passage refers to him, as our adversary. In this passage, the Holy Spirit reveals a number of truths to us, about our adversary, how he operates, and how the believer can deal with him. This book examines what God’s word says, on the subject of the believer’s authority over the devil in the earth.
