"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"
"For the body is not one member, but many. If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body? And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body? If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling? But now hath God set the members every one of them in the body, as it hath pleased him. And if they were all one member, where were the body? But now are they many members, yet but one body. And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you. Nay, much more those members of the body, which seem to be more feeble, are necessary: And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness. For our comely parts have no need: but God hath tempered the body together, having given more abundant honour to that part which lacked: That there should be no schism in the body; but that the members should have the same care one for another. And whether one member suffer, all the members suffer with it; or one member be honoured, all the members rejoice with it."
Both passages address the idea that individuals have different strengths and weaknesses. While 1 Corinthians 12 uses the analogy of the body to illustrate the importance of each member, EGW discusses the need to cultivate weak points. The underlying theme of diverse abilities and the need for balance connects the two passages.
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 bec…
"And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself."
The passage emphasizes the need to develop all faculties, reflecting the principle of loving God with all one's heart, soul, strength, and mind.
