Eden provides the setting for the biblical account of humanity's original relationship with God. Genesis 2 describes God forming Adam and placing him in the garden to work and keep it. Eve was subsequently created as his companion.
Genesis 3 records the serpent tempting Eve to eat from the forbidden tree. Adam also ate, bringing shame, alienation, judgment, and death into the human story. God expelled the couple from Eden and placed cherubim and a flaming sword to guard the way to the tree of life.
Later biblical writers use Eden as an image of extraordinary beauty, abundance, and divine blessing. The imagery of the tree of life reappears prominently in Revelation in the description of the restored creation.
