Urgency of Faith
Welcome back! Today we’re diving into Isaiah chapters 17–21. This passage is rich with prophetic imagery, historical tension, and spiritual urgency. Let’s jump past Damascus in chapter 17 and focus on Cush in chapter 18—a section that sparks fascinating theological debate.
Interpreting “Woe”
Maybe I’m a Bible geek, but I find it intriguing when great theologians disagree on Scripture. Isaiah 18:1 opens with, “Woe to the land of whirring wings along the rivers of Cush” (Isaiah 18:1, NIV). Most scholars agree this isn’t a warning in the traditional sense.
Albert Barnes suggests the word “woe” here is better understood as a salutation:
“This word… may be a mere interjection or salutation, and would be appropriately rendered by ‘Ho!’” ¹
Charles Ellicott adds:
“A new kingdom, hitherto unnamed by Isaiah, comes now within his horizon.” ² He deduces it is likely Egypt, though others argue for Ethiopia.
Despite the debate, the key takeaway remains clear. Matthew Henry writes:
“All the dwellers on earth must watch the motions of the Divine Providence, and wait upon the directions of the Divine will.” ³
Misplaced Trust
Isaiah is announcing Sennacherib’s eventual overthrow, and Hezekiah scrambles to form alliances with Cush, Egypt, or Ethiopia. The mistake? Seeking help from anyone other than God.
We’ve seen God deliver great nations into the hands of small groups of Jews. David often faced impossible odds but prevailed because he trusted in the God who was with him. Hezekiah, however, turns to idols and foreign gods for deliverance.
When we place our faith in anything other than God—perhaps “woe” is indeed a warning.
The Final Banner
Isaiah 18:3 paints a scene that echoes the last moments of history:
“All you people of the world… when a banner is raised on the mountains, you will see it, and when a trumpet sounds, you will hear it.” (Isaiah 18:3, NIV)
This aligns with Paul’s description of Christ’s return:
“For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise…” (1 Thessalonians 4:16–17, NIV) ⁴
Crowns Laid Down
Isaiah continues:
“At that time gifts will be brought to the Lord Almighty… to Mount Zion, the place of the Name of the Lord Almighty.” (Isaiah 18:7, NIV)
This mirrors the heavenly scene in Revelation:
“The twenty-four elders fall down before him who sits on the throne… They lay their crowns before the throne…” (Revelation 4:10, NIV) ⁵
It’s a picture of surrender and worship—of giving back to God what He has given us.
Obedience and Readiness
Then comes one of the most striking commands in Isaiah:
“Take off the sackcloth from your body and the sandals from your feet.” And he did so, going around stripped and barefoot. (Isaiah 20:2, NIV)
Isaiah remained this way for three years (Isaiah 20:3). I sure hope God doesn’t ask this of me—but if He did, we must be prepared to obey.
Those who don’t obey, who trust in worldly strength instead of divine protection, face a sobering fate:
“See what has happened to those we relied on… How then can we escape?” (Isaiah 20:5, NIV)
No Escape on That Day
We can’t. It’s that simple. When the trumpet sounds, there will be no escape. Your time to follow Jesus will have passed. Some may not live to see that day—none of us knows when our number is up.
We have but one day guaranteed: today. Don’t waste the opportunity to seek the Lord while you still can.
Tomorrow, we will read Isaiah 23-25.
