No one on this earth is without faith. It’s just a matter of where you put it.
God gave us reason as a gift, and meant that we should use it. That it has led some to worship “reason” as a god, while rejecting God Himself, is only what we might expect from a fallen world. Or they can worship “Science.”
All those things are idols. They function when used properly. But like the feller said, a doormat makes a mighty fine doormat but a mighty poor god.
