Malachi is the last book of the Old Testament. It was written about four hundred years before Jesus was born. The temple Haggai and Zechariah helped rebuild was standing again, but hearts had drifted. The book reads like an argument. The Lord says something, and the people push back with “Wherein?” That means “How? Prove it.” They do it again and again, in Malachi 1:2, 6–7, 2:17, 3:7–8 and 3:13. Teenagers will recognize the tone. And the Lord’s very first words aren’t a scolding: “I have loved you, saith the LORD,” in 1:2. His repeated invitation is “Return unto me, and I will return unto you,” in 3:7.
The priests were offering blind, lame and sick animals, the leftovers nobody wanted, in 1:7–8. The Lord asked if they’d dare give that to their governor. For youth, the leftovers question is easy to translate. The last half-awake minute of the day for prayer. Scriptures skimmed while scrolling. Sacrament meeting spent texting. The Lord wants their best because He wants their hearts, not because He needs their stuff.
Malachi 3:8–12 is the Old Testament’s great tithing passage. The Lord asks, “Will a man rob God?” He invites us to “prove me now herewith” and see if He won’t “open you the windows of heaven.” Today tithing is one-tenth of our increase, in Doctrine and Covenants 119:4. Many of your youth now earn money from babysitting, mowing or first jobs, so this is practical. They can fill out a donation slip and hand it to a bishopric member. Or they can pay online, with a parent’s help if needed. Tithing funds temples, meetinghouses and the Church’s work worldwide. The promised blessings are real but often spiritual and quiet. Peace, gratitude, stronger faith and help when it’s needed. It’s not a guarantee of money. Keep it honest and joyful, never guilt-driven.
Malachi ends with a promise: “I will send you Elijah the prophet.” He’ll turn the hearts of the fathers and the children to each other, in 4:5–6. The angel Moroni quoted it to Joseph Smith in 1823 with different wording. Elijah would reveal the priesthood. The promises made to the fathers would be planted in the children’s hearts. That’s Joseph Smith—History 1:38–39. On April 3, 1836, the Savior appeared in the Kirtland Temple to Joseph Smith and Oliver Cowdery. It was Easter Sunday, one week after the dedication. Moses, Elias and Elijah followed, and Elijah gave them the sealing keys. That’s Doctrine and Covenants 110. It was also Passover season, when many Jewish families traditionally watch for Elijah. Because of those keys, your youth can do baptisms for their own ancestors. Be sensitive. Some families aren’t sealed. Some are blended or adopted, and some are going through hard things. Every youth belongs to Heavenly Father’s family and can help gather it.
