In our pre-existent state, in our spiritual existence, I do not know how extensive our knowledge of good and evil was. That is not fully revealed. But this I do know that when we come to earth and become clothed with mortality, we do arrive at a knowledge of good and evil, and that knowledge prepares us for that future existence which we will have in the eternal worlds; it will enable us to enter upon a career that is never ending, that will continue onward and upward throughout all the ages of eternity. It is for this purpose that we are here. God has given unto us this probation for the express purpose of obtaining a knowledge of good and evil—of understanding evil and being able to overcome the evil—and by overcoming it receive the exaltation and glory that He has in store for us.
