“ Authentic Christianity and the world are by definition at odds. For most Americans, Christianity has been watered down and rendered innocuous, like so much fast food. It has become easy, upbeat, convenient, and compatible. It does not require self-sacrifice, discipline, humility, and otherworldly outlook, a zeal for souls, a fear as well as love of God. There is little guilt and no punishment, and the payoff in heaven is virtually certain.”
