Why Are There Murders and Suicides?
Eph 2:1 And you, though dead in your offenses and sins, (2)In which you once walked according to the age of this world, according to the ruler of the authority of the air, of the spirit which is now operating in the sons of disobedience; 6:12 For our wrestling is not against blood and flesh but against the rulers, against the authorities, against the world-rulers of this darkness, against the spiritual forces of evil in the heavenlies.
…The ruler here refers to Satan, the prince of the aerial authority mentioned in 6:12. The spirit, in apposition with “the authority of the air,” refers to the aggregate power, a personal aggregate of all the evil angelic authorities, over which Satan is the ruler. This aggregate spirit is now operating in the sons of disobedience. But we, who once were sons of disobedience, have been saved to be the church.
Above us there is the sphere ruled by Satan, the ruler of the authority of the air. Not many Christians have an adequate understanding of this evil power in the air. The entire earth is under the domination of this spirit in the air. This evil spirit, this evil atmosphere, is the cause of crimes, murders, and even suicides. It influences people to do evil things which, as humans, they would not normally do. The source of this evil is in the spirit, the atmosphere, which dominates them. This spirit is now operating in the sons of disobedience, in those who are disobedient to God.
