Part 1 - Covenants - Adam

Joseph Smith – discourse given before August 8, 1839:

I saw Adam in the valley of Ah-dam-ondi-Ahman—he called together his children & blessed them with a Patriarchal blessing. The Lord appeared in their midst, & he (Adam) blessed them all, & foretold what should befall them to the latest generation—See D.C. Sec III 28, 29 par —This is why Abraham blessed his posterity: He wanted to bring them into the presence of God. They looked for a city, &c. —Moses sought to bring the children of Israel into the presence of God, through the power of the Pristhood, but he could not. In the first ages of the world they tried to establish the same thing—& there were Elias's raised up who tried to restore these very glories but did not obtain them. But (Enoch did for himself & those that were with Him, but not for the world. J.T.) they prophesied of a day when this Glory would be revealed.—Paul spoke of the Dispensation of the fulness of times, when God would gather together all things in one &c &. Those men to whom these Keys have been given will have to be there. (I.E. when Adam shall again assemble his children of the Priesthood, & Christ be in their midst) the Ancient of Days come &c &c J.T.) And they without us cannot not be made perfect. These men are in heaven, but their children are on Earth. Their bowels yearn over us. God sends down men for this reason, Mat. 13. 41. & the Son of man shall send forth his Angels &c—All these authoritative characters will come down & join hand in hand in bringing about this work—The Kingdom of heaven is like a grain of mustard seed. the mustard seed is small but brings forth a large tree, and the fowls lodge in the branches The fowls are the Angels, the Book of Mormon perhaps, these Angels come down combined together to gather their children, & gather them. We cannot be made perfect without them, nor they without us when these things are done the Son of man will descend, the ancient of Days sit.

Joseph Smith - pre-written discourse, October 5, 1840:

Thus we behold the Keys of this priesthood consisted in obtaining the voice  of Jehovah that he talked with him in a familiare  and friendly manner, that he continued to him  the Keys, the Covenants, the power and the glory with which he blessed Adam at the beginning  and the offring of Sacrifice which also shall be  continued at the last time.

Denver Snuffer - 10/6/2013 - Centerville lecture on Covenants:

This is the original covenant. This is the first father. This is what was set in motion before the death of Adam, under the binding influence and ratification of the Holy Ghost (or the mind of God), in which Adam, under the influence of that Spirit, predicted whatsoever should befall his posterity unto the latest generation. This is the original covenant. This is the original father. Words spoken as a consequence of the influence of the Holy Spirit become the words of God because they are His. They will not fall to the ground unfulfilled. The new and everlasting covenant in our day, is "new" only as a consequence of it having been restored to our attention recently. It is not a new thing. It is a very old thing going back to the days of Adam. It was known to him. You were known to him. What was going to happen in your day was predicted and promised as a consequence of him. 

Prophecies as I've said before, revolve around two, and primarily two events only. The first was the coming of the Lord as a mortal, and the second is the coming of the Lord in judgment at the end of the world. There are plenty of prophecies that reckon to intermediate events, so you can find exceptions to the rule. It is nevertheless a rule, however, that the primary focus of all prophecy is the first and second coming of the Lord. These two events vindicate the promise the Father made at the beginning that He would redeem us all from the grave, and He promised further that at some point, the world  would come to an end as to its wickedness and there would be peace again on the earth. Everything revolves around those two prophetic events.

 Moses 6:64-68:

64 And it came to pass, when the Lord had spoken with Adam, our father, that Adam cried unto the Lord, and he was caught away by the Spirit of the Lord, and was carried down into the water, and was laid under the water, and was brought forth out of the water.

65 And thus he was baptized, and the Spirit of God descended upon him, and thus he was born of the Spirit, and became quickened in the inner man.

66 And he heard a voice out of heaven, saying: Thou art baptized with fire, and with the Holy Ghost. This is the record of the Father, and the Son, from henceforth and forever;

67 And thou art after the order of him who was without beginning of days or end of years, from all eternity to all eternity.

68 Behold, thou art one in me, a son of God; and thus may all become my sons. Amen.

D&C 107:53-57

53 Three years previous to the death of Adam, he called Seth, Enos, Cainan, Mahalaleel, Jared, Enoch, and Methuselah, who were all high priests, with the residue of his posterity who were righteous, into the valley of Adam-ondi-Ahman, and there bestowed upon them his last blessing.

54 And the Lord appeared unto them, and they rose up and blessed Adam, and called him Michael, the prince, the archangel.

55 And the Lord administered comfort unto Adam, and said unto him: I have set thee to be at the head; a multitude of nations shall come of thee, and thou art a prince over them forever.

56 And Adam stood up in the midst of the congregation; and, notwithstanding he was bowed down with age, being full of the Holy Ghost, predicted whatsoever should befall his posterity unto the latest generation.

57 These things were all written in the book of Enoch, and are to be testified of in due time.
