About
"This world" [in v. 2 above] refers to the satanic system composed of many ages. The word "age" here refers to a part, a section, an aspect, of the system of Satan, particularly the present and modern appearance of that system, which is used by him to usurp and occupy people and keep them away from God and His purpose. When we were dead in offenses and sins, we walked according to the age, the modern appearance, the present course, of the world, the satanic system.
