At the heart of the human condition, we might say, is an epistemological sin—the refusal to acknowledge what can be known about God and then to respond appropriately: “Although they knew God, they did not honor him as God or give thanks to him” (Rom. 1:21). They engage in willful blindness. ― Nancy Pearcey (from, Finding Truth: 5 Principles for Unmasking Atheism, Secularism, and Other God Substitutes)
