This is one of my favorite sections of the Doctrine and Covenants, and I think it is so cool to see in verse one, that this incredible doctrine is part of our scriptures today because of a righteous desire that Oliver had! Our loving Father in Heaven can give us revelation in accordance with our desires! I also think it is neat to see that in verse 3 the Lord tells Oliver to rely on the Book of Mormon. As much as I think it is important for each of us to rely on the word of God, I think this verse goes beyond that, I think the Lord is commanding us to rely on the testimonies that we have gained. Because when the world gets tough, we can always look back and find peace in the knowledge that we already have.
