We will not let it be desecrated or defaced in any way. We will control our diet and exercise for physical fitness. Just as physical strength requires exercise, so spiritual strength requires effort. Among the most important of spiritual exercises is prayer. It engenders harmony with God and a desire to keep His commandments.
Prayer is a key to wisdom, virtue, and humility.
We will be careful about which counsel we heed. Anyone who accepts direction contrary to the Word of Wisdom, for example, forsakes a law revealed to bring both physical and spiritual blessings. That caution pertains to pornography, which is highly addictive. In time, addictions enslave both the body and the spirit. Full repentance from addiction is best accomplished in this life, while we still have a mortal body to help us.
