The descendants of Adam soon began to exercise their free agency, some for, and many against, the Great Plan. Cain exercised his free agency in the murder of Abel. As time went on, large numbers departed from the truth concerning man's place in the universe as taught by Adam, and refused to accept the Gospel. Concurrently with the establishment of the Church in the first dispensation there was, therefore, a first great apostasy. It is ever so, it has ever been so, and will ever be so, that in a world of intelligent beings, possessing free agency, some will accept and some will reject the truth. No doubt, in the process of time, truth will triumph, and all may be brought to understand the will of God, but the conquest is attended by many temporary departures from the truth. Nevertheless, Adam and those who remained true to his teachings, continued, faithfully, to teach to others the eternal truth, so that they might perchance be made to return to the great truth which they had so lightly cast aside. **The Later Dispensations.** The first apostasy culminated in the flood, which was sent because of the violence of the first apostasy and the corruption of men. As far as known, only Noah and his immediate family were preserved. In them, however, was represented all the blood of the world. To the new race Noah explained fully that the flood was due, entirely, to the wicked hardness of the hearts of the people, and their refusal to accept eternal truth or to respect the authority of God, and that it was necessary, should calamity be avoided, to live in accordance with the Great Plan. To them all, the Gospel was taught in its purity. Nevertheless, it was only a short time before apostasy again occurred among many. The free agency of man can not be curbed. Yet, probably, there has not been, since the flood, such utter corruption as prevailed during the first apostasy. From the days of the flood, God or his messengers have appeared on earth, at various times, to restore the truth or to keep it alive in the hearts of the faithful, so that man might possess a full knowledge of the Gospel and that the earth might never need to be without the story of the Great Plan and the authority of the Priesthood. For instance, Melchizedek, the high priest, possessed a full measure of the authority of the holy priesthood. To Abraham, God and his angels appeared, and endowed him with the authority of God. So on, down the course of time, there are numerous instances of the appearance of God to men to help the children of men to a perfect understanding of the great truths that must be understood and obeyed, if men are to continue in their progressive development. It is not known how many men and women at various times have received such visitations, but it is probable that hosts of men and women at various times, even when the Church has not been organized, have received and used the truth of life as embodied in the Great Plan.
