The New Testament opens with two visits from the same angel. Zacharias, a priest serving his once-in-a-lifetime turn at the altar of incense, is told that he and Elisabeth, faithful and “well stricken in years,” will have a son named John (Luke 1:5–25). Six months later Gabriel tells Mary in Nazareth that she will be the mother of the Son of God (Luke 1:26–38). Both ask a question. Zacharias asks, “Whereby shall I know this?” and is left unable to speak until the promise comes true. Mary asks, “How shall this be?” and ends with, “Be it unto me according to thy word.” Matthew 1 adds Joseph’s side: a just man, a dream, and immediate obedience (Matthew 1:18–25).
Your class is 11 to 14, and for many of them this is week one as a deacon or in Young Women. Luke 1 is full of things they now touch: an Aaronic Priesthood holder serving in the temple, an angel ministering to him (the Aaronic Priesthood holds the keys of the ministering of angels, Doctrine and Covenants 13), prayer at the temple, and a promise to “turn the hearts of the fathers to the children” (Luke 1:17), which is exactly what they do in temple baptisms. The manual invites youth to notice how the Lord’s ancient Church looks like His restored Church.
The heart of the lesson is honest questions. Teens have real ones, and they need to hear that asking is not the problem. The difference between the two questions seems to be the heart behind them: Zacharias wanted proof before he would believe; Mary believed and asked how. Also be honest that Zacharias and Elisabeth were “blameless” (Luke 1:6) and still waited for years. Righteous people don’t always get what they want on their schedule, and that’s not a sign God forgot them.
Keep the doctrine clear: Jesus Christ is the literal Son of Heavenly Father and of Mary (Luke 1:31–35). If questions go further, it’s enough to say that it happened by the power of the Highest (Luke 1:35). His name was given by God “for he shall save his people from their sins” (Matthew 1:21), and one of His names, Emmanuel, means “God with us” (Matthew 1:23).
