Joel the LORD is God

To Judah. A horde of locusts can do as much damage as an invasion by a foreign army. Whether Joel is writing about actual locusts or using them as a metaphor for a future Assyrian invasion, the widespread devastation that is coming is a result of Judah’s sins.

The Day of the Lord will come with darkness, gloom, and thunder. But there was still time to repent and receive His kindness. The Lord will pour out His Spirit and everyone who calls on His name will be saved. Judah’s fortunes will be restored and the Lord will punish the nations who so viciously attacked her.
