Malachi is the last book of the Old Testament, written some decades after the second temple was finished, probably in the same era as Nehemiah. The excitement of rebuilding had worn off. Priests offered blind, lame and sick animals and called the whole thing a weariness (Malachi 1:8, 13). People held back tithes (3:8) and dealt treacherously with the wives of their youth (2:14). Nehemiah describes the same problems (Nehemiah 13:10–12, 23–27). Malachi’s name means “my messenger,” and his book is built as an argument: the Lord says something, the people push back with “Wherein?” (1:2, 6–7; 2:17; 3:7–8), and the Lord answers. It opens with “I have loved you” and the reply, in effect, “Prove it” (1:2).
Look for the Savior throughout. The Lord will send His messenger to prepare the way, and “the Lord, whom ye seek, shall suddenly come to his temple” (3:1); Jesus identified that messenger as John the Baptist (Matthew 11:10). He comes like a refiner’s fire, sitting patiently as a refiner of silver (3:2–3). Those who feared the Lord “spake often one to another,” and a book of remembrance was written for them (3:16). And for those who fear His name, “the Sun of righteousness” will “arise with healing in his wings” (4:2). The Savior taught Malachi 3–4 to the Nephites, because the Father commanded that they have it (3 Nephi 24–25).
The Old Testament ends with a promise: the Lord will send Elijah before the great and dreadful day of the Lord to turn the hearts of the fathers and the children to each other (Malachi 4:5–6). When Moroni visited Joseph Smith in 1823, he quoted it differently: the Lord would reveal the priesthood by the hand of Elijah, and he would plant in the hearts of the children the promises made to the fathers (Joseph Smith—History 1:36–39; see also Doctrine and Covenants 2). On April 3, 1836, in the Kirtland Temple, after the Savior appeared and accepted the temple, Elijah came and committed the keys of this dispensation’s sealing power to Joseph Smith and Oliver Cowdery (Doctrine and Covenants 110:13–16). It was Easter Sunday, in the season of Passover, when Jewish families have long hoped for Elijah’s return.
Twenty-five minutes goes quickly, and this is the last Sunday before Christmas. One story read well and one honest conversation will do more than a survey. Be tender with the turning-hearts discussion. Some in the room have painful or broken family relationships, no family in the Church, no spouse or children, or a loss this year. Turning hearts includes ancestors, the people who raised and love us now, and the family the Lord will give us in His time.
