If vainglory is about stealing glory from God, it is unintelligible outside the house of faith. This may explain why Rebecca DeYoung's book flows against the current of attempts to reclaim narcissism and pride.
I loved writing Wearing God in part because it allowed me to rove around archives from more or less every century of the Christian past. The biblical images for God that most (American?) churches today largely ignore were decidedly not ignored in earlier eras.
A few of the current candidates for president have remained members of the faith in which they were raised: Hillary Clinton (Methodist), Ben Carson (Seventh-day Adventist), and Rick Santorum (Catholic). Numerous other candidates have made a switch: Jeb Bush switched from the Episcopal to the Catholic Church. Rand Paul moved from the Episcopal Church to a Presbyterian church. Ted Cruz grew up in the home of lapsed Catholics until his father joined the Southern Baptists. Marco Rubio has migrated from the Catholic Church to Mormonism and back again to the Catholics, but sometimes goes with his Baptist spouse to her independent church. Bobby Jindal made the biggest switch: from the Hinduism of his youth to the Catholic faith (Newsweek, April 2).
