Think of the worst period in all of human history. Then listen to this message from the Book of Joel and hear about a time much worse than anything that ever happened before that is coming. Using historic events that have already occurred and future prophecies of what is to come, a time of devastation is predicted that will be difficult to bear. It includes a fierce invading army and involves fire and flames. God's promise, that if anyone repents and returns to God they will be loved and blessed, is offered also.
