When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul; discretion shall preserve thee, understanding shall keep thee. Proverbs 2:10, 11. RC 279.1
Now, as in the days of Israel, every youth should be instructed in the duties of practical life. Each should acquire a knowledge of some branch of manual labor by which, if need be, he may obtain a livelihood. This is essential, not only as a safeguard against the vicissitudes of life, but from its bearing upon physical, mental, and moral development. Even if it were certain that one would never need to resort to manual labor for his support, still he should be taught to work. Without physical exercise, no one can have a sound constitution and vigorous health; and the discipline of well-regulated labor is no less essential to the securing of a strong and active mind and a noble character.... RC 279.2
Let the youth be led to understand the object of their creation, to honor God and bless their fellow men; let them see the tender love which the Father in heaven has manifested toward them, and the high destiny for which the discipline of this life is to prepare them, the dignity and honor to which they are called, even to become the sons of God, and thousands would turn with contempt and loathing from the low and selfish aims and the frivolous pleasures that have hitherto engrossed them. They would learn to hate sin and to shun it, not merely from hope of reward or fear of punishment, but from a sense of its inherent baseness, because it would be a degrading of their God-given powers, a stain upon their Godlike manhood.... RC 279.3
The elements of character that make a man successful and honored among men—the irrepressible desire for some greater good, the indomitable will, the strenuous exertion, the untiring perseverance—are not to be crushed out. By the grace of God they are to be directed to objects as much higher than mere selfish and temporal interests as the heavens are higher than the earth. RC 279.4
And the education begun in this life will be continued in the life to come. Day by day the wonderful works of God, the evidences of His wisdom and power in creating and sustaining the universe, the infinite mystery of love and wisdom in the plan of redemption, will open to the mind in new beauty.... Even in this life we may catch glimpses of His presence and may taste the joy of communion with heaven, but the fullness of its joy and blessing will be reached in the hereafter. Eternity alone can reveal the glorious destiny to which man, restored to God's image, can attain.—Patriarchs and Prophets, 601, 602. RC 279.5
