Joel, son of Pethuel, was a native of Judah. Joel, means “Ya is God”, and his book is the second of the twelve Minor Prophets.
He was well-educated and he was a gifted poet and one of the books of the Bible is named after him. The Bible’s book of Joel has two main parts.
The first describes a locust plague and a drought. The second is more apocalyptic. Joel sees in both the locust plague and drought the judgment of God. Just as the locusts devoured the land, so will the land be devoured by enemy armies, unless the nation repents of its sins.
The Lord promises the people who repent, whether they are Jewish or non-Jewish, an ultimate deliverance from disaster.
Joel also warns punishment against the nations who have wronged the Jews, specifically, Tyre, Sidon, the Philistines, Egypt and Edom.
Joel mentions the great and terrible “Day of the Lord” which is in the future, but everyone who calls upon the name of the Lord will be saved.
In chapter 2, Joel makes the famous prediction of the Lord:
And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:
And also upon the servants and upon the handmaids in those days will I pour out my spirit.
And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.
The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.
And it shall come to pass, that whosoever shall call on the name of the LORD shall be delivered: For in mount Zion and in Jerusalem shall be deliverance, as the LORD hath said, and in the remnant whom the LORD shall call (Joel 2:28-32).
The theme of Joel’s message is one of coming judgment if Jerusalem does not repent. Joel also speaks of coming prosperity and final blessing, if the people respond in faith.
