Experience in one field does not automatically create expertise in another field. Expertise in religion comes from personal righteousness and from revelation. The Lord told the Prophet Joseph Smith: “All truth is independent in that sphere in which God has placed it.” (D&C 93:30) A geologist who has discovered truths about the structure of the earth may be oblivious to the truths God has given us about the eternal nature of the family.

If I can only make clear this one thing, it will give us a basis on which to build. Man cannot discover God or his ways by mere mental processes. One must be governed by the laws which control the realm into which he is delving. To become a plumber, one must study the laws which govern plumbing. He must know stresses and strains, temperatures at which pipes will freeze, laws which govern steam, hot water, expansion, contraction, and so forth. One might know much about plumbing and be a complete failure in training children or getting along with men. One might be the best of bookkeepers and yet not know anything of electricity. One might know much about buying and selling groceries and be absolutely ignorant of bridge building.

One might be a great authority on the hydrogen bomb and yet know nothing of banking. One might be a noted theologian and yet be wholly untrained in watchmaking. One might be the author of the law of relativity and yet know nothing of the Creator who originated every law. I repeat, these are not matters of opinion. They are absolute truths. These truths are available to every soul.

Any intelligent man may learn what he wants to learn. He may acquire knowledge in any field, though it requires much thought and effort. It takes more than a decade to get a high school diploma; it takes an additional four years for most people to get a college degree; it takes nearly a quarter-century to become a great physician. Why, oh, why do people think they can fathom the most complex spiritual depths without the necessary experimental and laboratory work accompanied by compliance with the laws that govern it? Absurd it is, but you will frequently find popular personalities, who seem never to have lived a single law of God, discoursing in interviews on religion. How ridiculous for such persons to attempt to outline for the world a way of life!

And yet many a financier, politician, college professor, or owner of a gambling club thinks that because he has risen above all his fellowmen in his particular field he knows everything in every field. One cannot know God nor understand his works or plans unless he follows the laws which govern. The spiritual realm, which is just as absolute as is the physical, cannot be understood by the laws of the physical. You do not learn to make electric generators in a seminary. Neither do you learn certain truths about spiritual things in a physics laboratory. You must go to the spiritual laboratory, use the facilities available there, and comply with the governing rules. Then you may know of these truths just as surely, or more surely, than the scientist knows the metals, or the acids, or other elements. It matters little whether one is a plumber, or a banker, or a farmer, for these occupations are secondary; what is most important is what one knows and believes concerning his past and his future and what he does about it.

When we were spiritual beings, fully organized and able to think and study and understand with him, our Heavenly Father said to us, in effect: “Now, my beloved children, in your spirit state you have progressed about as far as you can. To continue your development, you need physical bodies. I intend to provide a plan whereby you may continue your growth. As you know, one can grow only by overcoming.

“Now,” said the Lord, “we shall take of the elements at hand and organize them into an earth, place thereon vegetation and animal life, and permit you to go down upon it. This will be your proving ground. We shall give you a rich earth, lavishly furnished for your benefit and enjoyment, and we shall see if you will prove true and do the things that are asked of you. I will enter into a contract with you. If you will agree to exercise control over your desires and continue to grow toward perfection and godhood by the plan which I shall provide, I will give to you a physical body of flesh and bones and a rich and productive earth, with sun, water, forests, metals, soils, and all other things necessary to feed and clothe and house you and give to you every enjoyment that is proper and for your good. In addition to this, I will make it possible for you to eventually return to me as you improve your life, overcoming obstacles and approaching perfection.”

To the above most generous offer, we as sons and daughters of our Heavenly Father responded with gratitude. We took our turns and came to earth, as bodies were prepared by our earthly parents. We are now on trial—on the proving ground. This, also, is an absolute truth. It cannot be disproved. It is an incontrovertible fact. If one can accept these unassailable truths, then he is ready to start his experimentation and his laboratory work.

A few more salient facts, which I shall not attempt at this moment to elaborate upon: Adam and Eve transgressed a law and were responsible for a change that came to all their posterity, that of mortality. Could it have been the different food which made the change? Somehow blood, the life-giving element in our bodies, replaced the finer substance which coursed through their bodies before. They and we became mortal, subject to illness, pains, and even the physical dissolution called death. But the spirit, which is supreme in the dual man, transcends the body. It does not decompose but proceeds to the spirit world for further experience, with the assurance that after sufficient preparation there, a reunion will take place where the spirit will be housed eternally in a remodeled body of flesh and bones. This time the union will never be dissolved, since there will be no blood to disintegrate and cause trouble. A finer substance will give life to the body and will render it immortal.

This resurrection referred to is the work of Jesus Christ, the Savior, who, because he was both mortal (the son of Mary) and divine (the Son of God), was able to overcome the powers governing the flesh. He actually gave his life and literally took it up again as the “first fruits,” to be followed by every soul that has ever lived. Being a god, he gave his life. No one could take it from him. He had developed, through his perfection in overcoming all things, the power to take up his life again. Death was his last enemy, and he overcame even that and established the resurrection. This is an absolute truth. All the theorists in the world cannot disprove it. It is a fact.

Before his crucifixion, the Savior recognized the absolute necessity for an organization of persons duly empowered to carry on his work, teach his plan to the world, and persuade people to follow the eternal program. He therefore organized his Church among his faithful followers, with apostles, prophets, and other officials to give his people guidance. He sent those officials into all the world to teach his truths—but to teach them without using force, for the basic law of this world is free agency. Certainly men and women may use their free agency to do as they please, but they cannot ever evade the penalties that might come by reason of any error they make.
