This message, by Henry B. Eyring of the Quorum of the Twelve Apostles, is the most powerful. He tells a story of how he was asked to speak at a University. As the lady he was working with learned that his purpose and duty was to stand as a witness of Jesus Christ, she said, "You cannot fulfill your duty here". He then tells a story that is burned into my heart and mind. It instantly changes my heart and I want every word he says embedded in my mind. I want this talk to repeat in my head every single day.
"The only choice to be made was how to prepare"
