The purpose of the book of Amos was to announce God’s holy judgment on the Kingdom of Israel (the Northern Kingdom), call them to repentance, and to turn from their self-righteous sins and idolatry. God raised up the prophet Amos, as an act of His great mercy to a people who repeatedly shunned and disobeyed Him.
• Chapter 1-3, Amos came as the days of the wicked Northern Kingdom were winding down. The people were religious but it was sadly superficial. Amos announces that the neighboring nations would be punished. There were many of these wicked nations including Damascus, Gaza, Edom, and Tyre.
• In chapters 4-8, Amos warns that Israel will be destroyed, and gives examples of this judgment. Amos comes, announces God’s coming judgment to the Northern Kingdom and uses the phrase, “the day of the Lord” referring to God intervening to punish and judge the wicked city, which would eventually be exiled by the Assyrians.
“Seek good and not evil, that you may live; and thus may the LORD God of hosts be with you, just as you have said!” (5:14).
• In chapter 9, Amos tells of the restoration and hope of Israel, “In that day I will raise up the fallen booth of David, and wall up its breaches; I will also raise up its ruins And rebuild it as in the days of old” (9:11).
