Gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ. 1 Peter 1:13
We have each of us an individual work to do, to gird up the loins of our minds, to be sober, to watch unto prayer. The mind must be firmly controlled to dwell upon subjects that will strengthen the moral powers…. The thoughts must be pure, the meditations of the heart must be clean, if the words of the mouth are to be words acceptable to Heaven and helpful to your associates.
The mind should be guarded carefully. Nothing should be allowed to enter that will harm or destroy its healthy vigor. But to prevent this, it should be preoccupied with good seed, which, springing to life, will bring forth fruit-bearing branches…. A field left uncultivated speedily produces a rank growth of thistles and tangled vines, which exhaust the soil and are worthless to the owner. The ground is full of seeds blown and carried by the wind from every quarter; and if it is left uncultivated, they spring up to life spontaneously, choking every precious fruit-bearing plant that is struggling for existence. If the field were tilled and sown to grain, these valueless weeds would be extinguished, and could not flourish.
The youth who finds joy and happiness in reading the Word of God and in the hour of prayer is constantly refreshed by drafts from the Fountain of life. He will attain a height of moral excellence and a breadth of thought of which others cannot conceive. Communion with God encourages good thoughts, noble aspirations, clear perceptions of truth, and lofty purposes of action. Those who thus connect their souls with God are acknowledged by Him as His sons and daughters. They are constantly reaching higher and still higher, obtaining clear views of God and of eternity, until the Lord makes them channels of light and wisdom to the world.
