Summary of The Book of Joel

The prophet Joel showed up in Israel during a time of the most terrible plague of locusts in the nation's history. Joel came and prophesied to the land of Judah before the plague came. He warned the people of Judah that the devastation was going to sweep across the land very soon. He called for a season of fasting, mourning, and repentance. He warned them of God's judgment in the imagery of the impending invasion of locusts. He called the people of Judah and Jerusalem to weep over the sins, and to fast and repent because the day of the Lord is approaching. Soon the plague came and devastated the whole land and its effects were clearly seen and felt. The locusts came like a storm, they darkened the skies and every green thing was left barren. There was no hope of escape and they left utter decimation in their path. Joel seized upon the imagery of the locusts as a type of the greater judgement that would come on "the Day of the Lord" in the last days: Alas for the day! For the day of the LORD is at hand; it shall come as destruction from the Almighty . . . The LORD gives voice before His army, for His camp is very great; for strong is the One who executes His word. For the day of the LORD is great and very terrible; who can endure it? Joel 1:15, 2:11. Joel also gave a message of hope and prophesied of great blessings that would follow and the glories of the Messiah's kingdom.
