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. (3T 33.1) MC VC

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. (3T 33.2) MC VC
