From the April 1942 General Conference, prophet Heber J. Grant: 1
“MESSAGE TO THE YOUTH
To the youth of the Church we repeat all the foregoing advice, but above all we plead with you to live clean, for the unclean life leads only to suffering, misery, and woe physically, — and spiritually it is the path to destruction. How glorious and near to the angels is youth that is clean; this youth has joy unspeakable here and eternal happiness hereafter. Sexual purity is youth’s most precious possession; it is the foundation of all righteousness. Better dead, clean, than alive, unclean.
Times approach when we shall need all the health, strength, and spiritual power we can get to bear the afflictions that will come upon us.”
