Joseph teaches us so many great things about receiving personal revelation. The time involved, being determined to act, but I love the power that comes as Joseph determines to pray vocally. We are commanded to have a prayer in our heart always. But Doctrine and Covenants 19:28 also tells us that we must "pray vocally." As we do, as we say the desires of our hearts out loud, there is an extra measure of faith and devotion to our prayers.
