1. Repent before the day of judgment (1-3)
The prophet warns of God's wrath and of the coming judgment so that men may repent. What is repentance? It is to seek the Lord. The Lord can only be found by those who humble themselves to obey God's commands. Let us seek the Lord (3). This is the only way to escape the day of God's wrath.
2. Every nation will worship God (4-15)
The wrath of God is not reserved for the people of Judah. God loves the whole world. So his wrath is poured out on the surrounding nations of Philistia, Moab, Ammon, and Cush (Upper Nile) and on the mighty empire that was already cracking--Assyria. God will destroy the gods of every land so that the people of every nation might worship him (11). God eagerly wants all the world to fear him, love him, and worship him alone.
Application: Lord, give me a humble and contrite heart so that I may seek and find you. Bring the people of every nation to repentance and faith in Jesus.
One Word: Let all the world seek the Lord
