What is a worldview?  It is how we view and understand the world around us; how we live our lives in light of our worldview.  It is how we answer the big questions about God, humanity, life, death: Why is there evil in the world?  Suffering?  Death?  What is our biggest problem and what is the solution? 
Genesis 3 helps us answer these important questions.  God reveals the nature of sin in relation to Him.  He reveals Himself as the righteous Judge who deals with those who sin against Him.  He also displays His mercy and gives mankind hope for salvation.
