Remember, (1) the flesh has a sinful bent toward self-interest. It is committed to the question, “What’s in it for me?” (2) Satan is a liar and divider. Notice that the most explicit biblical teaching on spiritual warfare (Eph. 6) is found in the book that emphasizes unity. Satan’s most prominent strategy is to fracture and divide. And (3) the world tries to institutionalize these tendencies.
