Matthew 3, Mark 1 and Luke 3 introduce John the Baptist as an adult: the son of Zacharias from week 1, now preaching in the wilderness in camel’s hair, eating locusts and wild honey, and fulfilling Isaiah’s words, “Prepare ye the way of the Lord, make his paths straight” (Matthew 3:3). Crowds come to be baptized. When people ask, “What shall we do then?” John gives each group a specific, practical answer: share your extra coat and food, don’t cheat, don’t bully or lie, be content (Luke 3:10–14). Repentance for him isn’t a feeling; it’s “fruits meet for repentance” (Matthew 3:8), real change you can see.
Then Jesus comes to be baptized. John protests that he should be baptized by Jesus, not the other way around. Jesus answers that it becomes them “to fulfil all righteousness” (Matthew 3:15). Nephi later explains that even the sinless Son of God was baptized to show obedience to the Father and to show us the way (2 Nephi 31:5–9). As He comes out of the water, the heavens open, the Spirit descends like a dove, and the Father’s voice declares, “This is my beloved Son, in whom I am well pleased” (Matthew 3:16–17). Three separate members of the Godhead, all present at once. The dove was a sign; the Holy Ghost is a personage of spirit (Doctrine and Covenants 130:22).
This lesson is personal for your class. On May 15, 1829, the same John the Baptist appeared to Joseph Smith and Oliver Cowdery near the Susquehanna River and restored the Aaronic Priesthood, which holds the keys of the ministering of angels, of the gospel of repentance, and of baptism by immersion for the remission of sins (Doctrine and Covenants 13; Joseph Smith—History 1:68–72). The new deacons in your room hold that priesthood. They pass the sacrament, where everyone renews their baptism covenant. Young women and young men alike prepare the way through ministering, temple and family history work, and inviting friends to Christ.
Be careful not to let this become “are you a real repenter or a fake one?” Many teens are hard on themselves. Frame repentance as good news: John’s message was that the Lord is coming, so get ready and start changing. Slipping up isn’t failing; pretending not to need to change is the problem.
