They learned the hard way that without God, there's no meaning in life; no virtue, no morality, nothing of true value or goodness. You can say you're a believer, but live as an atheist; proclaiming God with your lips, but denying Him with your life. If you believe in God, then proclaim God by living a life by which God is Lord of every area. Because if He isn't, life isn't a whole lot better than a reign of terror.
