Since you ate the forbidden fruit, you are banished from the Garden of Eden.
Don't worry my children, I will save humanity from the damage caused by Satan's deception.
Mary is the new Eve and Christ is the new Adam.
"The Lord God then asked the women: What is this you have done? The women answered, "The snake tricked me, so I ate it." (Genesis 3:13) God gives Adam and Eve their punishments, such as painful childbirth and poor farmland. The snake also becomes a cursed animal.
Here is our appropriate offering, God!
"He expelled the man, stationing the cherubim in the fiery revolving sword east of the garden of Eden, to guard the way to the tree of life." (Genisis 3:24) So even as Adam and Eve are leaving the garden of Eden, God is already making a promise, a covenant, that he will save humanity from the damage caused by Satan's deception.
Why did God choose you? Mine was just as good.
God's promise of redemption involves Mary as the new Eve and Christ as the new Adam. They will restore the original holiness and justice that was lost by Adam and Eve. As the Mother of God, Mary is the first to benefit from Christ's victory over sin. She is conceived without Original Sin and remains free from sin her entire life.
I will protect you, my child.
Cain and Abel were the sons of Adam and Eve. Both of them offered the appropriate sacrifice to God. God liked Abel's sacrifice better since it was the best of what he raised.
Cain was jealous because God favored Abel's sacrifice. Due to his anger, Cain killed his brother.
God tried to warn Cain to not let sin be his master. After the murder, God marked Cain to prevent anyone from killing him in revenge. God's promise to save the descendants of Adam and Eve is already taking place.
