I love the book of Abraham. It is enlightening. This is one of my favourites:
In the Pearl of Great Price. The Book of Abraham, Chapter 3 verses 22 to 27 we read:
22 Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the Noble and Great ones;
23 And God saw these souls that they were good, and He stood in the midst of them, and He said: These I will make my rulers; for He stood among those that were Spirits, and he saw that they were good; and He said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born.
24 And there stood one among them that was like unto God, and He said unto those who were with Him: We will go down, for there is space there, and we will take of these materials, and we will make an earth whereon these may dwell;
25 And we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them;
26 And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever.
27 And the Lord said: Whom shall I send? And one answered like unto the Son of Man: Here am I, send me. And another answered and said: Here am I, send me. And the Lord said: I will send the first.
