Joel, Amos, and Obadiah all anticipate the day of the Lord. In that day, God will first judge his own people for their sin and rebellion, holding them to a higher standard because they have received the Word of God. Next, that day will bring judgment upon the nations. The nations will be judged not only for their treatment of God’s people but also for whether they adhered to the laws and ways of God, which are plainly evident in creation.
Nevertheless, despite the judgment accompanying the day of the Lord, it will be a day of hope for God’s people. On that day, God will firmly establish his rule over all nations and will vindicate his people through the exercise of his justice. That day, then, will ultimately be a day of renewal in which the shame and reproach of God’s people will be removed and what was once lost will be fully restored in abundance.
Joel’s anticipation of the day of the Lord begins with the people’s lament over a devastating locust plague, which Joel uses to illustrate the devastation that the coming judgment, through an enemy army coming from the north, will bring upon Israel. However, if God’s people repent and turn back to God, rending their hearts before him, he will come and destroy that invading army and bring about a time of refreshment for his people. In that time, the shame of God’s people will be removed, the years the locust ate will be restored, and, more importantly, the people will be reconciled to their God, a reconciliation anticipating the future day in which God will pour out his Holy Spirit upon all who call on his name. The book of Joel ends with the anticipation of the day of the Lord, in which God will bring judgment upon the nations, that is, upon those who are God’s enemies and the enemies of his people.
Amos, conversely, begins with the judgment of the nations. However, after building the joyful anticipation of Israel over the destruction of their enemies, Amos turns suddenly and proclaims that Israel, too, will be subject to God’s judgment. Through a series of four oracles and two visions, Amos denounces Israel’s false worship, because the people neglect daily justice and righteousness; he also denounces their complacency, arrogance, and self-indulgence, especially their extravagance at the expense of the weak and impoverished. Even so, the day of the Lord is an object of hope for God’s people, and the book of Amos ends with a third vision through which God promises to raise up the booth of David, to gather his people from every nation, and to protect them from ever again being uprooted. That day will be one of such blessing from God that the land itself will overflow with abundant provisions from him.
The day of the Lord in the book of Obadiah concentrates on God’s judgment against Edom for participating and reveling in the destruction of God’s people by Babylon’s army. This judgment will bring about the vindication of God’s people for the evil done to them by Edom. Although Obadiah is a very short book focusing on God’s judgment against Edom, it also contains the hopeful aspect of the day of the Lord through Obadiah’s anticipation of the rule of the King over all nations.
Throughout Israel’s history, glimpses can be seen of the fulfillment of that promised day of the Lord. For example, with Cyrus’s decree in 538 BC, the Jews exiled to Babylon were granted permission to return to the Promised Land and to begin rebuilding their lives. The defeat of Babylon and the return to the land were a partial fulfillment of the day of the Lord and a glimpse of what was yet to come. However, the people were still awaiting the complete fulfillment of the prophetic promise. Obadiah notes that saviors shall go up to Mount Zion, and in the fullness of time the one final Savior, Jesus Christ, would come and be lifted up for the salvation of his people. And one day, Jesus will return for the final day of the Lord, as King of kings and Lord of lords. On that great day, everyone will give an answer for his or her deeds, beginning with the people of God. And then, after the judgment of the nations, God’s people will dwell with him forever, “And they shall never again be uprooted” (Amos 9:15).
