The Book of Joel is the twenty-ninth book of the Bible and one of the Minor Prophets.

It delivers a powerful prophetic message using the imagery of a devastating locust plague to warn of a coming Day of the Lord—a time of judgment and salvation.

The book moves from disaster to deliverance, offering hope for those who repent.

Joel speaks to every generation, reminding us that God uses crisis to call us back to Himself and that He is merciful and ready to restore.

A Locust Plague and Call to Repentance (Joel 1)

Joel opens with a vivid description of a historic locust invasion that wipes out the land, symbolizing God’s judgment.
