Like a good detective, let's examine this book.

🔥 Overview

The book of Joel is a powerful prophetic message centered on a devastating locust plague that strikes Judah. The prophet uses this disaster to call the people to repentance, warning of an even greater judgment called the "Day of the Lord." But Joel doesn’t stop at judgment—he offers hope, promising that God will restore what was lost and pour out His Spirit on all people. Though short (only 3 chapters), Joel packs in a rich blend of warning, worship, and promise.

🔍 Things to Notice

The locusts — more than just insects, they symbolize an invading army and God's judgment.
The recurring phrase “Day of the Lord” — a time of both judgment and deliverance.
Call to communal repentance — including priests, elders, and the entire nation.
The promise of restoration — God will repay the years the locusts devoured (Joel 2:25).
Outpouring of the Spirit — a prophecy fulfilled in Acts 2 at Pentecost.
