Genesis 2 gives us another perspective on creation with an emphasis on man. Man is given the land to cultivate, and Adam is given Eve to help him. God instructs Adam not to eat the fruit of the tree of knowledge of good and evil, but he eats deliberately, knowing that this is a sin, and that it is grave matter. This meets the criteria of mortal sin. We can see the effects of Adam’s sin immediately after, when Cain slays Abel.
