Known as “God’s salesman,” Peale merged worldliness and godliness to produce an easy-to-follow theology that preached self-confidence as a life philosophy. Critics called him a con man, described his church as a cult, and said his simple-minded approach shut off genuine thinking or insight. But Peale’s outlook, promoted through his radio shows, newspaper columns and articles, and through Guideposts, his monthly digest of inspirational messages, fit perfectly into the Trump family culture of never hesitating to bend the rules, doing whatever it took to win, and never, ever giving up.
