Is it true that Adam and his wife did not know that they were physically naked before sin? I.e. the terms 'naked' and 'clothed' did not exist unto then.
"And the man and his wife were both naked and were not ashamed" (Genesis 2:25). Adam and Eve were like little children in this respect. A child might run around after a bath without clothes and not think anything of it. He knows he is not wearing anything, but he also doesn't understand that there is a need to wear something. It was not until Adam and Eve sinned that they realized the significance of being without clothes. "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 loin coverings" (Genesis 3:7).
