I think what impresses me the most about Christ's miracle at the wedding in Cana is not that He turned water into wine, but that He would fulfill His mother's wishes, even though it wasn't yet time for Him to begin His mortal ministry. He could have pulled something like, "I'm the Son of God and the Savior of the World, and you want me to do what?" Instead, He recognized that He is the Son of Mary just as much as He is the Son of God. The commentary in the Institute manual about why Christ called His mother "woman" only serves to impress me even more. It shows to me how much He loves and respects His earthly mother, and recognizes her role in the events that set the Atonement in motion.
When Christ cleansed the temple and then taught His disciples about how our bodies are temples, I think He was saying something about the sacredness of all temples, including our bodies. When I think of it in that light, reading John 2:16 causes me to stop and think. He says, "Make not my Father's house an house of merchandise." I tried to think of this in context for my body. In what ways do we make our bodies "houses of merchandise?" I think that perhaps we do this whenever we treat our bodies or the bodies of others as objects, toys, or playthings. Some people sell their own bodies for others' entertainment, while some people sell other people. These are the grosser crimes, but I wonder if mistreating our own body counts as making it a "house of merchandise." Whenever we put our body at risk or deliberately try to trigger certain emotions like adrenaline for our entertainment, we are making our body a "house of merchandise." I think that Christ is saying that we need to cleanse ourselves of these kind of behaviors, and instead make our body a house of God.
