The youth especially should feel that they must train their minds, and take every opportunity to become intelligent, that they may render acceptable service to Him who has given His precious life for them. And let no one make the mistake of regarding himself as so well educated as to have no more need of studying books or nature.
Let everyone improve every opportunity with which in the providence of God he is favored, to acquire all that is possible in revelation or science. We should learn to place the proper estimate on the powers that God has given us. If a youth has to begin at the lowest round of the ladder, he should not be discouraged, but be determined to climb round after round until he shall hear the voice of Christ saying, “Child, come up higher. Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy Lord.” ...
Young men and women, have you, as individuals purchased at infinite cost, sought to study to show yourselves approved unto God, workmen which need not be ashamed? Have you brought to God the precious talent of your voice, and put forth painstaking effort to speak clearly, distinctly, and readily? ... The Lord, who made man perfect in the beginning, will help you to cultivate your physical and mental powers, and fit you to bear burdens and responsibilities in the cause of God.—Fundamentals of Christian Education, 213-215.
Life is not given to us to be spent in idleness or self-pleasing, but great possibilities have been placed before every one who will develop his God-given capabilities.—Fundamentals of Christian Education, 416. WGD 112
Minds that have been given up to loose thought need to change. “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; as obedient children, not fashioning yourselves according to the former lusts in your ignorance: but as He which hath called you is holy, so be ye holy in all manner of conversation; because it is written, Be ye holy; for I am holy.” 1 Peter 1:13-16. MH 455
Study to shew thyself
approved unto God, a workman that needeth not to be ashamed, rightly
dividing the word of truth. 2 Timothy 2:15, KJV
