God has committed to each of us sacred trusts, for which He holds us accountable. It is His purpose that we so educate the mind as to be able to exercise the talents He has given us in such a manner as to accomplish the greatest good and reflect the glory to the Giver. We are indebted to God for all the qualities of the mind. These powers can be cultivated, and so discreetly directed and controlled as to accomplish the purpose for which they were given. It is duty to so educate the mind as to bring out the energies of the soul and develop every faculty. When all the faculties are in exercise, the intellect will be strengthened, and the purpose for which they were given will be accomplished. 1TT 293.1
Many are not doing the greatest amount of good because they exercise the intellect in one direction and neglect to give careful attention to those things for which they think they are not adapted. Some faculties that are weak are thus allowed to lie dormant because the work that should call them into exercise, and consequently give them strength, is not pleasant. All the powers of the mind should be exercised, all the faculties cultivated. Perception, judgment, memory, and all the reasoning powers should have equal strength in order that minds may be well balanced. 1TT 293.2
If certain faculties are used to the neglect of others, the design of God is not fully carried out in us; for all the faculties have a bearing and are dependent, in a great measure, upon one another. One cannot be effectually used without the operation of all, that the balance may be carefully preserved. If all the attention and strength are given to one, while others lie dormant, the development is strong in that one and will lead to extremes, because all the powers have not been cultivated. Some minds are dwarfed and not properly balanced. All minds are not naturally constituted alike. We have varied minds; some are strong upon certain points and very weak upon others. These deficiencies, so apparent, need not and should not exist. If those who possess them would strengthen the weak points in their character by cultivation and exercise they would become strong. 1TT 293.3
It is agreeable, but not most profitable, to exercise those faculties which are naturally the strongest, while we neglect those that are weak, but which need to be strengthened. The feeblest faculties should have careful attention, that all the powers of the intellect may be nicely balanced and all do their part like well-regulated machinery. We are dependent upon God for the preservation of all our faculties. Christians are under obligation to Him to so train the mind that all the faculties may be strengthened and more fully developed. If we neglect to do this, they will never accomplish the purpose for which they were designed. We have no right to neglect any one of the powers that God has given us. We see monomaniacs all over the country. They are frequently sane upon every subject but one. The reason of this is that one organ of the mind was specially exercised while the others were permitted to lie dormant. The one that was in constant use became worn and diseased, and the man became a wreck. God was not glorified by his pursuing this course. Had he exercised all the organs equally, all would have had a healthy development; all the labor would not have been thrown upon one, therefore no one would have broken down. 1TT 294.1
Ministers should be guarded, lest they thwart the purposes of God by plans of their own. They are in danger of narrowing down the work of God, and confining their labor to certain localities, and not cultivating a special interest for the work of God in all its various departments. There are some who concentrate their minds upon one subject to the exclusion of others which may be of equal importance. They are one-idea men. All the strength of their being is concentrated on the subject upon which the mind is exercised for the time. Every other consideration is lost sight of. This one favorite theme is the burden of their thoughts and the theme of their conversation. All the evidence which has a bearing upon that subject is eagerly seized and appropriated, and dwelt upon at so great length that minds are wearied in following them. 1TT 294.2
Time is frequently lost in explaining points which are really unimportant, and which would be taken for granted without producing proof; for they are self-evident. But the real, vital points should be made as plain and forcible as language and proof can make them. The power to concentrate the mind upon one subject to the exclusion of all others is well in a degree; but the constant exercise of this faculty wears upon those organs that are called into use to do this work; it throws too great a tax upon them, and the result is a failure to accomplish the greatest amount of good. The principal wear comes upon one set of organs, while the others lie dormant. The mind cannot thus be healthfully exercised, and, in consequence, life is shortened. 1TT 295.1
All the faculties should bear a part of the labor, working harmoniously, balancing one another. Those who put the whole strength of their mind into one subject are greatly deficient on other points, for the reason that the faculties are not equally cultivated. The subject before them enchains their attention, and they are led on and on, and go deeper and deeper into the matter. They see knowledge and light as they become interested and absorbed. But there are very few minds that can follow them unless they have given the subject the same depth of thought. There is danger of such men plowing, and planting the seed of truth so deep that the tender, precious blade will never find the surface. 1TT 295.2
Much hard labor is often expended that is not called for and that will never be appreciated. If those who have large concentrativeness cultivate this faculty to the neglect of others, they cannot have well-proportioned minds. They are like machinery in which only one set of wheels works at a time. While some wheels are rusting from inaction, others are wearing from constant use. Men who cultivate one or two faculties, and do not exercise all equally, cannot accomplish one half the good in the world that God designed they should. They are one-sided men; only half of the power that God has given them is put to use, while the other half is rusting with inaction. 1TT 295.3
If this class of minds have a special work, requiring thought, they should not exercise all their powers upon that one thing, to the exclusion of every other interest. While they make the subject before them their principal business, other branches of the work should have a portion of their time. This would be much better for themselves and for the cause generally. One branch of the work should not have exclusive attention to the neglect of all others. 1TT 296.1
In their writings some need to be constantly guarded, that they do not make points blind that are plain, by covering them up with many arguments which will not be of lively interest to the reader. If they linger tediously upon points, giving every particular which suggests itself to the mind, their labor is nearly lost. The interest of the reader will not be deep enough to pursue the subject to its close. The most essential points of truth may be made indistinct by giving attention to every minute point. Much ground is covered; but the work upon which so much labor is expended is not calculated to do the greatest amount of good, by awakening a general interest. 1TT 296.2
In this age, when pleasing fables are drifting upon the surface and attracting the mind, truth presented in an easy style, backed up with a few strong proofs, is better than to search and bring forth an overwhelming array of evidence; for the point then does not stand so distinct in many minds as before the objections and evidences were brought before them. With many, assertions will go further than long arguments. They take many things for granted. Proof does not help the case in the minds of such. 1TT 296.3
