ISB ~ Ephesians 2 v2

power of the air:Paul assumes the ancient belief that demonic spirits crowd the atmosphere, posing an ominous and ongoing threat to our spiritual lives. The prince among them is Satan, the archenemy of God, who is veiled from our sight but is not thereby any less real or dangerous (4:27; 6:11; Jn 8:44). Man is powerless to resist the domination of the devil without the assistance of grace (Eph 6:11-17). See note on Eph 6:10-17.

sons of disobedience:A Hebraism meaning “rebels” or “sinners” (5:6).
