The prophet Joel was sent to proclaim God’s judgment upon His Old Testament people for their idolatry. He predicts a “locust” plague that will devastate the nation. But with the judgment the LORD also offers an invitation and a call to repentance to His sinful people. Our summary verse is from Joel 2:32: “Whoever calls on the name of the LORD shall be saved.” – (NKJV)
