Norman Vincent Peale popularized what came to be known as positive thinking. He took existing ideas from Christian Science and other inspirations, gave them a biblical veneer, integrated them with psychology, and packaged them for the masses, spreading his message through The Power of Positive Thinking and his other works. His foremost contribution to the world was this notion that thoughts are causative, that our thoughts can change our lives, our health, our destiny. Readers were thrilled with this notion that if they believed it, they could have it, or be it, or do it.
Peale believed we live in a world that is mental more than physical and this allows our thoughts to be determinative. If this is the case, all that stands between us and our desires is properly controlling our thoughts. In one of his books he taught the importance of a form of mental activity called imaging. It consists of vividly picturing, in your conscious mind, a desired goal or objective, and holding that image until it sinks into your unconscious mind, where it releases great, untapped energies. It works best when it is combined with a strong religious faith, backed by prayer, and the seemingly illogical technique of giving thanks for benefits before they are received. When the imaging concept is applied steadily and systematically, it solves problems, strengthens personalities, improves health, and greatly enhances the chances for success in any kind of endeavor.

None of this would be remarkable, except that he taught it as a minister who claimed to be a Christian. Yet as a Christian minister he denied that God was a being, saying “Who is God? Some theological being? He is so much greater than theology. God is vitality. God is life. God is energy. As you breathe God in, as you visualize His energy, you will be reenergized!” (Plus: The Magazine of Positive Thinking). As a Christian minister he told Phil Donahue, “It’s not necessary to be born again. You have your way to God, I have mine. I found eternal peace in a Shinto shrine … I’ve been to Shinto shrines and God is everywhere. … Christ is one of the ways! God is everywhere.” He denied the very heart of the Christian faith and replaced it with his doctrine of positive thinking.
