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 distinguish between right and wrong internally. The moral responsibility of human beings 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 certainly affected by sin throughout life, but it remains embedded in the human psyche. One question that both atheists and evolutionists continue to struggle with is how to adequately explain the moral nature of humans, cultures, and every human being.
