A love for the world begins in the soul… It begins with a dull conscience and a listless soul. Sin does not grieve him like it once did. Passion for the Savior begins to cool. Affections grow dim. Excitement lessens for participating in the local church. Eagerness to evangelize starts to wane. Growth in godliness slows to a crawl.
– C. J. Mahaney, Worldliness: Resisting the Seduction of a Fallen World, p. 20
