Book excerpt: American Christians are facing uncertain times. Our nation's values are under assault. Religious liberty has been undermined. We live in a day when right is now wrong and wrong is now right. The vicious leftwing attack against the recent traditional marriage stance of Chick-fil-A should serve as a wakeup call to people of faith. It's not about a chicken sandwich. It's about religious liberty. It's about free speech. It's about the future of our nation.
