What does it mean to “Like your body”?
If the picture below is anything to go by, to “Like your body” means to go naked. I can see why: When a person is naked, they are showing all that they are to the world. They are saying “This is me” without shame.
The naked body is inherently good, and we (human beings) were meant to be naked without shame:
God saw all that he had made, and it was very good.
And the man and his wife were both naked and were not ashamed.
