Amos 3:6 means calamity, not sin: God is holy, sovereign, and righteous in judgment over nations and cities.
Amos 6–9 reveals Israel’s judgment for pride, false worship, and oppression, yet ends with hope: God restores David’s fallen kingdom.
Amos warns that God judges all nations, exposes hypocrisy, and calls His people to seek the Lord, uphold justice, and live.
