In Job, chapter one, verses six through seven, before the death and resurrection of Christ, Satan had occasional access to the presence of God, whereby he could question the sincerity and righteousness of a believer, as in this chapter one, verses six through twelve, chapter two, verses one through six, chapter thirty-eight, verse seven, and Revelation twelve, verse ten, respectively.
Satan stands for serpent: an accuser, tormentor, and adversary who does most of his evil activity at night. This fallen angel was great and created perfect. He was appointed to minister on the throne before the world began but rebelled and became the chief antagonist of God and humanity, as in Ezekiel twenty-eight, verses twelve through fifteen.
In his rebellion against God, Satan drew with him a multitude of lesser angels, as in Revelation twelve, verse four, whose identification after the fall with demons and evil spirits. Satan and many of these lesser angels were exiled to the earth and the atmosphere around it and operated within this sphere under God’s permissive will. Satan, known as the serpent, caused the human race to fall to sin.
Satan’s kingdom, as in chapter twelve, verse twenty-six, is a highly systemized empire of evil that has authority over the kingdom of the air, as in Ephesians two, verse two, fallen angels, as in Matthew twenty-five, verse forty-one, and Revelation twelve, verse seven, unregenerate humanity, as in Matthew four, verses eight to nine, John twelve, verse thirty-one, and Ephesians two, verse two, and the world, as in Luke four, verse five through six, and Second Corinthians four, verse four. However, Satan is not omnipresent, omnipotent, or omniscient. Therefore, most of his assignments are to do evil activity to demons, as in Matthew eight, verse twenty-eight, Revelation sixteen, verses thirteen to sixteen, accordingly.
Satan presently wars against God and His people, as in Job chapters one through two, and Ephesians six, verses eleven through eighteen, respectively.
