If you believe that you don’t need God to know what is right or wrong, that humans are just an accident of nature with no more value than a rock, have no issue with people like Stalin, Hitler or Mao Tse-Tung who all killed millions upon millions of humans based on these same assumptions, then read no further.
There are things that we will never understand about God. They remain a mystery to the human mind. Even our language that is based on familiar things to us cannot begin to describe or understand these mysteries. We can however describe some important “attribute” of God that helps us to shed a small bit of light on His Nature.
