In speaking with the Prophet Joseph once on this subject, he traced it from the first down to the last, until he got to the Ancient of Days. He wished me to write something for him on this subject, but I found it a very difficult thing to do. He had to correct me several times. We are told that the "judgment shall sit and the books be opened." He spoke of the various dispensations and of those holding the keys thereof, and said there would then be a general giving up or accounting for. I wrote that each one holding the keys of the several dispensations would deliver them up to his predecessor, from one to another, until the whole kingdom should be delivered up to the Father, and then God would be "all in all." Said he, "That is not right." I wrote it again, and again he said it was not right. It is very difficult to find language suitable to convey the meaning of spiritual things. The idea was that they should deliver up or give an account of their administrations, in their several dispensations, but that they would all retain their several positions and Priesthood. The Bible and Doctrine and Covenants speaks about certain books which should be opened; and another book would be opened, called the Book of Life, and out of the things written in these books would men be judged at the last day.
