What does Joel teach about judgment and deliverance?

The book of Joel presents a profound message regarding God's judgment and the promise of deliverance. Specifically, Joel 3 describes the day of the Lord as a time when God will gather all nations for judgment. This stark warning highlights the seriousness of sin and the consequences faced by the unrepentant. However, the text is equally clear about the deliverance offered to God's people, reassuring them that while judgment is inevitable for those who reject Him, He will protect and redeem His elect. This duality underscores the richness of God's grace and righteousness, reminding believers to remain steadfast in faith while waiting for their ultimate rescue and transformation.
