Individual salvation requires that a man must repent and accept the fulness of the Gospel if he would be exalted in the kingdom of God. This plan of salvation was taught to Adam after his expulsion from the Garden of Eden. He was baptized in water for the remission of his sins, in the name of the only Begotten of the Father, and received the Holy Ghost. He and his wife, Eve, were commanded to teach their children the Gospel, that they also “might be sanctified from all sin, and enjoy the words of eternal life in this world, and eternal life in the world to come, even immortal glory” (Moses ch. 6).
In obedience to this commandment Adam and Eve made all these things known to their sons and daughters. Thus the Gospel was taught in the beginning and was declared from generation to generation. Adam received the Holy Priesthood, which was also conferred upon the patriarchs who followed after him. They were “preachers of righteousness, and spake and prophesied, and called upon all men, everywhere, to repent, and faith was taught unto the children of men” (Moses 6:22).
The Gospel Rejected in Days of Noah
In the days of Noah the Gospel was universally rejected, save by Noah and his immediate family—in all eight souls. Noah had labored diligently and long to bring mankind to repentance, but without avail, “for all flesh had corrupted his way upon the earth” (Moses 8:29). After the destruction of the wicked in the flood, the Gospel continued to be taught by Noah and the later patriarchs, but quite generally it was not received. Melchizedek, king of Salem, through his faithfulness, became a great high priest, and the people of the Church in his day honored him by calling the “Holy Priesthood after the order of the Son of God,” by his name, “out of respect or reverence to the name of the Supreme Being” (D. & C. 107:4). From Melchizedek, Abraham received the Priesthood, and to Melchizedek, as the properly authorized servant of the Lord, Abraham paid tithes of all he possessed (Gen. 14:20).
The Covenant with Abraham
Unto Abraham also was the Gospel preached and the Lord made covenant with him that through him and his posterity should all nations of the earth be blessed (Gen. 22:18). This same Gospel was also declared to the children of Israel in its simple truth; but they proved unworthy to receive it in its fulness, due to their long sojourn in Egypt, where they had partaken of the customs, traditions and theology of the Egyptians, and therefore “the word preached did not profit them, not being mixed with faith in them that heard it” (Heb. 4:2). The Lord endeavored to establish the fulness of his Gospel and authority among them, which Moses plainly taught, and he sought to sanctify the people, “that they might behold the face of God; but they hardened their hearts and could not endure his presence, therefore the Lord in his wrath (for his anger was kindled against them) swore that they should not enter into his rest while in the wilderness, which rest is the fulness of his glory” (D. & C. 84:23–24).
The Higher Priesthood and the Carnal Law
It became necessary, therefore, for the Lord to take Moses and the Higher Priesthood out of their midst, but the Lesser Priesthood, which holds the keys of the ministering of angels and the preparatory Gospel—faith, repentance and baptism for the remission of sins—he permitted to remain. To this he added the carnal law, known as the law of Moses, which was added, so Paul informs us, as a schoolmaster to prepare them to receive the fulness of the Gospel when restored by Jesus Christ.
The Israelites, from the time they entered the promised land to the coming of the Son of God, were living under the law of Moses, which laid upon them severe and exacting restrictions because of their refusal to receive the fulness of the Gospel when it was offered in the wilderness. When the Savior came, it was to complete and fulfil the ends of this law, of which he said not one jot or title should pass until all was fulfilled.
