Malachi is the last book of the Old Testament, written about four centuries before Christ. The temple Haggai and Zechariah pushed the people to finish is standing. But the excitement is gone. The book is built as a back-and-forth. The Lord makes a statement, and the people push back with “Wherein?” Then the Lord answers. See Malachi 1:2, 6–7, 2:17, 3:7–8 and 3:13. It opens with “I have loved you,” and the people basically reply, “Prove it,” in 1:2. That honest, slightly defensive tone will sound familiar to teenagers. That’s the point. The Lord keeps answering and keeps inviting: “Return unto me, and I will return unto you,” in 3:7.
The priests offered blind, lame and sick animals. They called the whole thing a weariness, in 1:8 and 1:13. The Lord asks if their governor would accept that. He wants a pure offering, in 1:11. That means our real best, not leftovers. Then comes tithing: “Will a man rob God?” in 3:8–12. For youth earning their first paychecks, this is practical. Tithing is one-tenth of our increase, in Doctrine and Covenants 119:4. Elder David A. Bednar gave a talk in October 2013 called “The Windows of Heaven.” He taught that the promised blessings are often quiet and practical. They’re not usually a sudden flood of money. Near the end of each year, the bishop meets with members for tithing declaration. Families often go together.
Malachi ends with the Old Testament’s final promise. The Lord will send Elijah before the great and dreadful day of the Lord. He’ll turn the hearts of the fathers and the children to each other, in 4:5–6. When Moroni visited Joseph Smith in 1823, Joseph was 17. That’s the age of many in your class. Moroni quoted this prophecy with a difference. The Lord would reveal the priesthood by the hand of Elijah. And Elijah would plant in the hearts of the children the promises made to the fathers. See Joseph Smith—History 1:36–39. Elijah came to Joseph Smith and Oliver Cowdery in the Kirtland Temple on April 3, 1836. The Savior had just appeared and accepted the temple. Then Elijah gave them the sealing keys, in Doctrine and Covenants 110:13–16.
Connect this to where your youth are right now. “The promises made to the fathers” include God’s covenant with Abraham, in Abraham 2:9–11. A patriarchal blessing declares a person’s lineage in the house of Israel. So it ties them to those promises. Temple work for their ancestors, family history and their own future sealing all flow from Elijah’s keys. Be sensitive. Some youth have complicated or painful family situations. Turning hearts includes the people who raise and love them now. It includes ancestors they’ve never met, and the family they’ll build one day.
