"The book of Joel makes it loud and clear that natural disaster is not some accident, but rather the Lord is the ultimate cause behind it all." from video introduction.
"Date of Writing: The Book of Joel was likely written between 835 and 800 B.C.
Purpose of Writing: Judah, the setting for the book, is devastated by a vast horde of locusts. This invasion of locusts destroys everything—the fields of grain, the vineyards, the gardens and the trees. Joel symbolically describes the locusts as a marching human army and views all of this as divine judgment coming against the nation for her sins. The book is highlighted by two major events. One is the invasion of locusts and the other the outpouring of the Spirit. The initial fulfillment of this is quoted by Peter in Acts 2 as having taken place at Pentecost.
Key Verses:
Joel 1:4, "What the locust swarm has left the great locusts have eaten; what the great locusts have left the young locusts have eaten; what the young locusts have left other locusts have eaten."
Joel 2:25, "I will repay you for the years the locusts have eaten..."
Joel 2:28, "And afterward, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your old men will dream dreams, your young men will see visions.".." from the article: Summary Book of Joel
