The prophecy of Joel is about a coming disaster in Israel, the hope of repentance and reformation, and the promise of international justice. We do not know the full nature of the hardship we are facing, but we know that it is from the Lord. It is for our good, it is for His glory, and it is part of His plan to fill the earth with the knowledge of the Lord as the waters cover the sea. But one of the great lessons of Joel is the centrality of worship to all of life. Joel confronts our national sin of thinking that worship is not related to plagues, politics, economics, and family life.
