Chastity and Sanctity of Life.

"THE FIRST COMMANDMENT that God gave to Adam and Eve pertained to their potential for parenthood as husband and wife. We declare that God’s commandment for His children to multiply and replenish the earth remains in force. We further declare that God has commanded that the sacred powers of procreation are to be employed only between man and woman, lawfully wedded as husband and wife.

WE DECLARE the means by which mortal life is created to be divinely appointed. We affirm the sanctity of life and of its importance in God’s eternal plan."

Elder Bednar: Things as They Really Are. May 2009 

Because a physical body is so central to the Father’s plan of happiness and our  spiritual development, we should not be surprised that Lucifer seeks to frustrate  our progression by tempting us to use our bodies improperly. One of the ultimate ironies of eternity is that the adversary, who is miserable precisely because he  has no physical body, invites and entices us to share in his misery through the  improper use of our bodies. The very tool he does not have and cannot use is  thus the primary target of his attempts to lure us to physical and spiritual 
destruction.

The adversary attempts to influence us both to misuse our physical bodies and to minimize the importance of our bodies. These two methods of attack are  important for us to recognize and to repel.

When any of Heavenly Father’s children misuse their physical tabernacles by  violating the law of chastity, by using drugs and addictive substances, by  disfiguring or defacing themselves, or by worshiping the false idol of body image, whether their own or that of others, Satan is delighted.
