This is a warning to all of us, living after the Book of Mormon comes forth, about how we can have no secrets from the Lord. We think we can get away, unobserved, with a little wickedness. In the privacy of our homes, viewing the internet, we think we can gratify our baser instincts. But, in the end, since God created us and loans to us the power to live, and move and breathe, He sees with clarity everything in our hearts. It is another way of reminding us of our need to repent.
