In this sermon Jesus, The More Excellent Sacrifice, Adam and Eve sinned. And they proceeded to try and deal with it in their own ingenuity. They "covered up". Anyone who disobeys God is going to feel naked within. God took Adam and Eve, and stripped away their man-made coverings. He took an innocent lamb and shed its blood to provide a covering for them. God clothed them, and blessed them. Every time Adam and Eve would see each other from then on, they would be reminded of the covering provided at the death of an innocent. Reminded of what God did for them in their trouble. And when God lovingly clothed them, the work gave them peace. They would not have to run away again.
