Doctrine & Covenants Section 76: Any man may know through that revelation what his part and condition will be.

 I consider that the Doctrine and Covenants, our Testament, contains a code of the most solemn, the most Godlike proclamations ever made to the human family. I will refer to the “Vision” [in section 76] alone, as a revelation which gives more light, more truth and more principle than any revelation contained in any other book we ever read. It makes plain to our understanding our present condition, where we came from, why we are here, and where we are going to. Any man may know through that revelation what his part and condition will be. For all men know what laws they keep, and the laws that men keep here will determine their position hereafter; they will be preserved by those laws and receive the blessings that belong to them.²⁰
