I just listened to a fantastic CES Fireside by Elder David A. Bednar. He spoke of the sacredness of our bodies, taking an approach that I hadn't considered before. Of particular interest to me were his words describing the way in which Satan strives to diminish the importance of our physical bodies, and our relationships with those around us, through enticing us to become addicted to technology such as video games, social networks, and other mediums of virtual reality. He spoke plainly and raised a powerful warning voice. I highly recommend his address to everyone. Here's the link:
