Key points:
1. The events described in Joel, particularly the locust plague and the army of the Lord, are yet to be fulfilled in the future during the end times.
2. The army in Joel 2 is connected to the locusts from the bottomless pit in Revelation 9, suggesting a supernatural and apocalyptic event.
3. The Valley of Jehoshaphat mentioned in Joel 3 is likely the same as the Valley of Megiddo (Armageddon) described in Revelation 16.
4. The current age of grace, in which believers live, is distinct from the events prophesied in Joel, which concern God's dealings with Israel and the end times.
5. Studying the minor prophets is crucial for understanding God's plan for Israel and the end times, and provides assurance for believers in the current age.
