"The Prophet Joseph Smith tells us that God himself, finding that he was in the midst of spirits and glory, ordained laws whereby they might advance and progress and become like him. Those laws included the creation of this earth; they included the receipt of a mortal body where we could be tried and tested in a probationary state and receive experiences impossible to gain in any other way; they included the opportunity to choose between right and wrong, to do good or to do evil, the opportunity to grow and advance in the things of the spirit; and they included the opportunity to enter into a marriage relationship that has the potential of being eternal. We started out on this course in the premortal life. Now we are down here taking the final examination for all the life that we lived back then, which also is the entrance examination for the realms and kingdoms that are ahead."
