President Dallin H. Oaks - Kingdoms of Glory

 Concerning the three degrees of glory, President Oaks taught - 

"The Apostle Paul taught that the Lord’s teachings and commandments were given that we may all attain “the measure of the stature of the fulness of Christ.”23 That process requires far more than acquiring knowledge. It is not even enough to be convinced of the gospel; we must act so that we are converted by it. In contrast to other preaching, which teaches us to know something, the gospel of Jesus Christ challenges us to become something.

From such teachings we conclude that the Final Judgment is not just an evaluation of a sum total of good and evil acts—what we have done. It is based on the final effect of our acts and thoughts—what we have become. We qualify for eternal life through a process of conversion. As used here, this word of many meanings signifies a profound change of nature. It is not enough for anyone just to go through the motions. The commandments, ordinances, and covenants of the gospel are not a list of deposits required to be made in some heavenly account. The gospel of Jesus Christ is a plan that shows us how to become what our Heavenly Father desires us to become."
