Isaiah 40 opens a new section of the book with one word the rest of it keeps returning to: “Comfort.” These chapters speak to Judah’s future exiles in Babylon, people who would see Jerusalem and its temple destroyed (about 586 BC) and would wonder whether God had walked away from them. Isaiah even names Cyrus, the Persian king who would conquer Babylon in 539 BC and let the Jews go home to rebuild (Isaiah 44:28; 45:1; Ezra 1:1–4). Nephi had chapters 48–49 on the brass plates before the exile ever happened and read them to his family (1 Nephi 19:23; 20–21), and the risen Savior told the Nephites that “great are the words of Isaiah” (3 Nephi 23:1).
This lesson centers on Isaiah 40, one of the great chapters of the Old Testament. It moves in a deliberate arc: a message of pardon (40:1–2), a voice preparing a highway for the Lord in the desert (40:3–5), which all four Gospels apply to John the Baptist (see Luke 3:2–6), the fading grass beside the enduring word (40:6–8), a Shepherd carrying lambs (40:11), and then page after page of God’s sheer greatness: the oceans in the hollow of His hand, the nations “as a drop of a bucket,” every star called by name (40:12, 15, 26). All of that builds to the people’s real complaint, “My way is hid from the Lord” (40:27), and the Lord’s answer in verses 28–31.
Two word notes help adults with 40:31. The Hebrew verb behind “wait upon” carries the sense of hopeful expectation, looking eagerly toward someone, not sitting idle. And the word translated “renew” can also mean “exchange”: those who wait on the Lord trade their spent strength for His. Notice the order, too: mount up, run, walk. Some seasons feel like flying. Many ordinary weeks are simply walking and not fainting, and Isaiah counts that as a promise kept.
The rest of the block is rich with the same comfort: “Fear thou not; for I am with thee” (41:10); a Servant who will not break a bruised reed (42:3); “when thou passest through the waters, I will be with thee” (43:2); the sharp satire of a man who bakes bread over half a log and bows to the other half (44:9–20); idols that have to be carried, set beside a God who carries us “even to hoar hairs” (46:1–4); refining “in the furnace of affliction” (48:10); and names graven on the palms of His hands (49:16). Twenty-five minutes won’t hold them all; read Isaiah 40 well and let the class find the rest this week.
