Seeing your body as your temple can positively influence your decisions about how you will care for your body and how you will use it

 “Each time you look in the mirror, see your body as your temple. That truth—refreshed gratefully each day—can positively influence your decisions about how you will care for your body and how you will use it.”

"Decisions for Eternity"

By Elder Russell M. Nelson

Of the Quorum of the Twelve Apostles
