good and evil.
This is the moral code which is essential for navigating the human experience. From day to day, every decision made is either good which nurtures righteousness, or evil which fuels sinfulness and pride.
And out of the ground the Lord God made every tree grow that is pleasant to the sight and good for food. The tree of life was also in the midst of the garden, and the tree of the knowledge of good and evil.
Genesis 2:9
