Matthew 6 opens with a warning that fits the age of social media perfectly: don’t do good things “to be seen of them” (6:1). Jesus names three religious habits, giving to the poor, praying and fasting, and shows how each can become a performance. People who do them for applause “have their reward” (6:2, 5, 16); the applause is all they get. But the Father “which seeth in secret” rewards openly (6:4, 6, 18). The rest of the chapter asks where our treasure and hearts are (6:19–21), says we can’t serve two masters (6:24), and tells anxious people to consider the lilies and the birds, because the Father knows what we need (6:25–34). Be careful with that last part: worry is real, and for some youth anxiety is a health condition that needs care. The Savior’s point is that they are known and loved, not that anxious people lack faith.
Matthew 7:1 sounds like “never judge anything,” but the Joseph Smith Translation clarifies it as judging not unrighteously but with righteous judgment (compare John 7:24). The mote-and-beam image (7:3–5) is almost comic: a man with a plank in his eye trying to pick a speck out of someone else’s. Jesus then invites us to ask, seek and knock (7:7–11), gives the Golden Rule (7:12), and teaches that false prophets are known “by their fruits” (7:15–20), a useful test for the endless claims youth see online. In 7:21–23 the JST changes “I never knew you” to “Ye never knew me”: it’s about knowing Him, not just saying the right words.
The sermon ends with two builders (7:24–27). Both heard the same words. The same rain, floods and wind hit both houses. The only difference was what each did with what he heard. The manual points youth to pages 4–5 of For the Strength of Youth: A Guide for Making Choices, which is about building on Jesus Christ as a foundation, and to Helaman 5:12. The crowd was astonished because He taught “as one having authority” (7:29). For 14–16s, the heart of this week is authenticity: an audience of one, and a faith that is lived, not posted.
