Ephesians 2:1 And you He made alive, who were dead in trespasses and sins, 2 in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, 3 among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.
Verses 1-3 focus on fallen man, and his hopeless condition (dead) as a result of his sin.
If Ephesians 1:19-23 takes us to the heights in exploring the power and authority of the risen and ascended Christ, Ephesians 2:1-3 takes us to the very depths, as Paul gives a detailed explanation of the powerless, hopeless, lifeless condition of fallen men, enslaved by their own fleshly desires, and controlled by the world around them and by Satan. The irony of fallen man’s dilemma is that he doesn’t even realize his condition until after he is saved. Lost men, blinded and deceived by Satan, think they are really “living it up,” when in reality they are dead. They think that by living in sin they are enjoying life to its fullest, but they are not. They suppose that they are free, subject to no one, but they are really enslaved.
