Here again students at BYU have the advantage of being taught both ancient and modern revelation. Twenty centuries before Christ a revelation to Abraham disclosed the whole intricate operation of what appears to have been our own galaxy. In the center he was shown Kolob, a great stellar giant which Abraham was told the Lord "set . . . to govern all those which belong to the same order as that upon which thou [Abraham] standest [the earth]" (Book of Abraham 3:3). Abraham was shown the wheels within wheels of the vast organization of stellar systems and the "set time" of the important ones. He saw one system rise above another until it reached the central power plant called Kolob that operates according to "the reckoning of the Lord's time; which Kolob is set nigh unto the throne of God, to govern all those planets which belong to the same order as that upon which thou standest" (Book of Abraham 3:9). The ancient patriarch then concludes, "Thus I, Abraham, talked with the Lord, face to face, as one man talketh with another; and he told me of the works which his hands had made" (verse 11). A few hundred years later a similar revelation was given to Moses, and he noted that among the vast creations of God there were many "lands," each of which was called an "earth," and "there were inhabitants on the face thereof" (Book of Moses 1:29). When Moses asked about these many creations and these numerous inhabited planets, God replied, "Only an account of this earth, and the inhabitants thereof, give I unto you. For behold, there are many worlds that have passed away by the word of my power. And there are many that now stand, and innumerable are they unto man; but all things are numbered unto me, for they are mine and I know them" (Book of Moses 1:35).
