[Note: This refers to Satan, whose influence permeates life around us]. He is the [evil] spirit who is now at work in people who are disobedient [to God].

[Remember] that you were at that time without Christ; [you were] excluded from citizenship in the nation of Israel; [you were] foreigners regarding the Agreements of [God's] promises. You had no hope and were without God in the world.

For our struggle is not [actually] against human beings, but against rulers and authorities and leaders of this world's darkness, and against the spiritual forces of evil in the heavenly realms. [Note: "Heavenly realms" here refers to the struggle against Satanic powers which permeates life around us].
