We're going to have a discussion, a family discussion. It'll be just a bit more formal because we've invited 14,000 friends. And here are my great-grandparents, your grandparents, Dad. Yes. On the day we met in 1963 I had just turned 11. Lena Sophia, my grandmother, was 87. In 1917 my grandfather Leander died of tuberculosis, leaving Lena Sophia a widow and pregnant with their 10th child. Think about the strength and comfort Lena Sophia must have gained from knowing about the sealing power, that that power is given direction as we research and learn about our ancestors. This kind of reminds me of some of the history of explosives. In 1847 the Italian chemist Ascanio Sobrero concocted a completely new explosive material, nitroglycerin. But it is incredibly unstable. A few decades later Alfred Nobel found that he could absorb liquid nitroglycerine into a stabilizing material called kieselguhr and he named the new material dynamite. Dynamite wasn't the discovery of a new material but it involved putting two known materials together to make them safer, more effective and more useful. Without family history, the sealing authority can't get where it needs to be to be used. And the true value of family history is only realized because of the sealing authority. Both can be meaningful in our lives but just like nitroglycerine and kieselguhr, the real power comes when we combine family history with the blessings of the temple. Do either of you remember the challenge that Elder Neil L. Anderson gave at RootsTech two years ago? His apostolic temple challenge continued to grow this year. Brothers and sisters, I promise you protection for you and your family as you take this challenge to find as many names to take to the temple as ordinances you perform in the temple, and teach others to do the same. So it's not just baptisms. That's right, not just baptisms but all temple ordinances. Sounds like nobody's off the hook. Nobody's off the hook. And if you accept this challenge, blessings will begin to flow to you and your family. You'll find not only protection from the temptation and ills of this world, but you'll also find personal power, power to change, power to repent, power to learn, power to be sanctified and power to turn the hearts of your family together and heal that which needs healing.
