The holiness of God is no secret. When God created humanity, He created us with a moral compass that would allow each of us to consciously differentiate between good and evil internally. The moral responsibility of humans is what makes them accountable to God for their actions. We saw this in Genesis when Adam and Even ate from the tree of knowledge. I believe it is safe to say that the mind of conscience is definitely struck by sin throughout life, but it remains ingrained in the human psyche. A question that atheists and evolutionists continue to struggle with is how to adequately explain the moral nature of humans, cultures, and each world.
