D&C 130:20-21 There is a law, irrevocably decreed in heaven before the foundations of this world, upon which all blessings are predicated-- And when we obtain any blessing from God, it is by obedience to that law upon which it is predicated.	D&C 130:22-23 The Father has a body of flesh and bones as tangible as man's; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit. Were it not so, the Holy Ghost could not dwell in us. A man may receive the Holy Ghost, and it may descend upon him and not tarry with him.
D&C 131:1-4 In the celestial glory there are three heavens or degrees; And in order to obtain the highest, a man must enter into this order of the priesthood [meaning the new and everlasting covenant of marriage]; And if he does not, he cannot obtain it. He may enter into the other, but that is the end of his kingdom; he cannot have an increase.	D&C 137:7-10 Thus came the voice of the Lord unto me, saying: All who have died without a knowledge of this gospel, who would have received it if they had been permitted to tarry, shall be heirs of the celestial kingdom of God; Also all that shall die henceforth without a knowledge of it, who would have received it with all their hearts, shall be heirs of that kingdom; For I, the Lord, will judge all men according to their works, according to the desire of their hearts. And I also beheld that all children who die before they arrive at the years of accountability are saved in the celestial kingdom of heaven.
Joseph Smith History 1:15-20 After I had retired to the place where I had previously designed to go, having looked around me, and finding myself alone, I kneeled down and began to offer up the desires of my heart to God. I had scarcely done so, when immediately I was seized upon by some power which entirely overcame me, and had such an astonishing influence over me as to bind my tongue so that I could not speak. Thick darkness gathered around me, and it seemed to me for a time as if I were doomed to sudden destruction. But, exerting all my powers to call upon God to deliver me out of the power of this enemy which had seized upon me, and at the very moment when I was ready to sink into despair and abandon myself to destruction--not to an imaginary ruin, but to the power of some actual being from the unseen world, who had such marvelous power as I had never before felt in any being--just at this moment of great alarm, I saw a pillar of light exactly over my head, above the brightness of the sun, which descended gradually until it fell upon me. It no sooner appeared than I found myself delivered from the enemy which held me bound. When the light rested upon me I saw two Personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other--This is My Beloved Son. Hear Him! My object in going to inquire of the Lord was to know which of all the sects was right, that I might know which to join. No sooner, therefore, did I get possession of myself, so as to be able to speak, than I asked the Personages who stood above me in the light, which of all the sects was right (for at this time it had never entered into my heart that all were wrong)--and which I should join. I was answered that I must join none of them, for they were all wrong; and the Personage who addressed me said that all their creeds were an abomination in his sight; that those professors were all corrupt; that: "they draw near to me with their lips, but their hearts are far from me, they teach for doctrines the commandments of men, having a form of godliness, but they deny the power thereof." He again forbade me to join with any of them; and many other things did he say unto me, which I cannot write at this time. When I came to myself again, I found myself lying on my back, looking up into heaven. When the light had departed, I had no strength; but soon recovering in some degree, I went home. And as I leaned up to the fireplace, mother inquired what the matter was. I replied, "Never mind, all is well--I am well enough off." I then said to my mother, "I have learned for myself that Presbyterianism is not true." It seems as though the adversary was aware, at a very early period of my life, that I was destined to prove a disturber and an annoyer of his kingdom; else why should the powers of darkness combine against me? Why the opposition and persecution that arose against me, almost in my infancy?
