19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.
Substances such as alcohol, tobacco, and harmful drugs are forbidden by the Lord. We have similarly been warned about the evils of pornography and unclean thoughts. Appetites for these degrading forces can become addictive. In time, physical or mental addictions enslave both the body and the spirit. Repentance from such shackles should be accomplished in this life while we still have the aid of a mortal body to help us develop self-mastery.
When we truly know our divine nature, we will want to control such appetites. And we will focus our eyes on sights, our ears on sounds, and our minds on thoughts that are a credit to our physical creation as a temple of God. In daily prayer, we will gratefully acknowledge Him as our Creator and thank Him for the magnificence of our own physical temple. We will care for it and cherish it as our own personal gift from God.
"Now, I ask you, … are you more interested in dressing and grooming your body to appeal to the world than to please God? Your answer to this question sends a direct message to Him about your feelings regarding His transcendent gift to you”
- President Russell M. Nelson
Satan would have us forget that we are created in the image of our Heavenly Parents and that our eternal worth does not depend on what we look like.
The adversary knows that fixating on our bodies is a distraction from more important matters: our values, our relationships with other people, and our relationship with God.
Our Creator put appetites in our bodies to perpetuate the human race and fulfill His great plan of happiness. Thus, we have appetites for food, for water, and for love.
Satan knows the power of our appetites. So, he tempts us to eat things we should not eat, to drink things we should not drink, and to desecrate the most intimate expressions of love by employing them outside the bounds of marriage.
