Did you notice the phrase, prince of the power of the air in Ephesians 2:1-6? The word prince means chief; power means authority. The word worketh is energeo in Greek. It means something that is active and efficient. In other words, there was an energy that worked in each one of us before we received Jesus; it drove us into sin. The chief authority and driver of that sinful energy, who functions in the atmosphere around the earth, is Satan.
When the Bible uses the word heaven, you have to ask yourself, “Which heaven?” The first heaven is the one Paul referred to in Ephesians 2:1-6 when he used the word air; it is the atmosphere around the earth. The second heaven is what we call outer space. Satan operates within these first two heavens.
Practical Application
Satan and his demons work within the atmospheres around the earth, but his greatest effort is against your mind! He knows if he can get you into doubt and fear, he can have access to every area of your life! Cast down imaginations and every high thing that doesn’t agree with God’s Word! (2 Corinthians 10:5)
