Question 157: What is meant by the “prince of the power of the air”?

Answer:

It refers to Satan (Ephesians 2:2), the "prince of evil," who assails men on earth with trials and temptations. The word "power" is used here for the embodiment of that evil spirit which is the ruling principle of all unbelief, especially among the heathen. (See 1 Timothy 4:1; 2 Corinthians 4:4; John 12:31.)
