God bestows upon us talents for wise improvement, not for abuse. Education is but a preparation of the physical, intellectual, and moral powers for the best performance of all the duties of life. Improper reading gives an education that is false. The power of endurance, and the strength and activity of the brain, may be lessened or increased according to the manner in which they are employed. There is a work before you to dispose of your light reading. Remove it from your house. Do not have before you the temptation to pervert your imagination, to unbalance your nervous system, and to ruin your children. By much reading you are unfitting yourself for the duties of a wife and mother, and, in fact, are disqualifying yourself to do good anywhere. 1TT 570.2
The Bible is not studied as it should be; therefore you do not become wise in the Scriptures and are not thoroughly furnished unto all good works. Light reading fascinates the mind and makes the reading of God's word uninteresting. You seek to make others believe that you are conversant with the Scriptures; but this cannot be, for your mind is filled with rubbish. The Bible requires thought and prayerful research. It is not enough to skim over the surface. While some passages are too plain to be misunderstood, others are more intricate, demanding careful and patient study. Like the precious metal concealed in the hills and mountains, its gems of truth are to be searched out and stored in the mind for future use. Oh, that all would exercise their minds as constantly in searching for celestial gold as for the gold that perishes! 1TT 571.1
When you search the Scriptures with an earnest desire to learn the truth, God will breathe His Spirit into your heart and impress your mind with the light of His word. The Bible is its own interpreter, one passage explaining another. By comparing scriptures referring to the same subjects, you will see beauty and harmony of which you have never dreamed. There is no other book whose perusal strengthens and enlarges, elevates and ennobles the mind, as does the perusal of this Book of books. Its study imparts new vigor to the mind, which is thus brought in contact with subjects requiring earnest thought, and is drawn out in prayer to God for power to comprehend the truths revealed. If the mind is left to deal with commonplace subjects, instead of deep and difficult problems, it will become narrowed down to the standard of the matter which it contemplates and will finally lose its power of expansion. 1TT 571.2

God is displeased with those who are too careless or indolent to become efficient, well-informed workers. The Christian should possess more intelligence and keener discernment than the worldling. The study of God's word is continually expanding the mind and strengthening the intellect. There is nothing that will so refine and elevate the character, and give vigor to every faculty, as the continual exercise of the mind to grasp and comprehend weighty and important truths. 1TT 571.3
The human mind becomes dwarfed and enfeebled when dealing with commonplace matters only, never rising above the level of the things of time and sense to grasp the mysteries of the unseen. The understanding is gradually brought to the level of the subjects with which it is constantly familiar. The mind will contract its powers and lose its ability if it is not exercised to acquire additional knowledge and put to the stretch to comprehend the revelations of divine power in nature and in the Sacred Word.—1881, Testimonies for the Church 4:545, 546. 1TT 572.1
