Introduction to the Book of Joel in the Bible
The Book of Joel reminds us that God rules over every nation and calls His people to return to Him. Through a devastating locust plague, Joel warns Judah about God’s coming judgment and the Day of the LORD. Yet, amid these warnings, God reveals His mercy and promises restoration to those who sincerely repent.

We will discover how God uses difficult circumstances to awaken His people and call them to repentance.

1. The Author of Joel
The prophet Joel wrote the Book of Joel, the second of the twelve Minor Prophets. His name means “The LORD is God.” Joel identifies himself as the son of Pethuel (Joel 1:1). Scripture provides few details about his personal life, family, or background. However, God appointed Joel to proclaim His Word to His people.
Joel directed his message primarily to Judah and Jerusalem. His frequent references to the temple, priests, and worship suggest that he lived in Judah, possibly Jerusalem (Joel 1:13–14; 2:15–17). Joel emphasized God’s holiness, His righteous judgment, and His willingness to forgive those who sincerely repent. (Source Material: William MacDonald, Believer’s Bible Commentary, pp. 1107-1108)
2. Historical Background of Joel
Joel ministered during a devastating locust plague and severe drought that destroyed Judah’s crops (Joel 1:4–12). These disasters brought widespread suffering and disrupted temple worship. Joel called the people to recognize God’s warning, humble themselves, and seek His mercy through genuine repentance (Joel 1:13–14; 2:12–13).
The exact date of Joel’s ministry remains uncertain because he mentions no reigning king. Some conservative scholars place his ministry around 835–800 BC, during the reign of King Joash. Others favor a date after the Babylonian exile, around the fifth century BC. Regardless of the date, Joel connected Judah’s suffering with God’s coming judgment. (Source Material: John MacArthur, The MacArthur Bible Commentary, pp. 983-985)
3. The Themes of Joel
The central theme of Joel is “The Day of the LORD” (Joel 1:15; 2:1, 11; 3:14). This day involves God’s judgment against sin and His ultimate victory over evil. Joel also emphasizes repentance, God’s mercy, and spiritual restoration. He urges God’s people to return wholeheartedly to Him rather than merely practice outward religion (Joel 2:12–13).
Joel also reveals God’s future purposes for Israel and the nations. He promises restoration, the outpouring of the Holy Spirit, and judgment against Israel’s enemies (Joel 2:25–32; 3:1–21). Peter connects Joel’s prophecy with Pentecost (Acts 2:16–21). Joel’s message ultimately points toward God’s faithfulness and His future kingdom blessings for Israel. (Source Material: John F. Walvoord and Roy B. Zuck, The Bible Knowledge Commentary: Old Testament, pp. 1409-1413)

The Book of Joel reminds us that God remains sovereign over history and faithful to His promises. Through Joel’s message, we discover how God warned Judah about coming judgment and called His people to repentance.

As we reflect on Joel’s message, we must examine our hearts and respond to God’s Word. God calls us to turn from sin, seek His mercy, and trust His promises.
