Q.16: Did our first parents continue in the estate wherein they were created?
A. Our first parents being left to the freedom of their own will, fell from the estate wherein they were created, by sinning against God.
So when the woman saw that the tree was good for food, that it was pleasant to the eyes, and a tree desirable to make one wise, she took of its fruit and ate. She also gave to her husband with her, and he ate. Then the eyes of both of them were opened, and they knew that they were naked; and they sewed fig leaves together and made themselves coverings. And they heard the sound of the LORD God walking in the garden in the cool of the day, and Adam and his wife hid themselves from the presence of the LORD God among the trees of the garden. Genesis 3:6-8
And the LORD God said to the woman, “What is this you have done?” The woman said, “The serpent deceived me, and I ate.” Genesis 3:13
