ATTENTION! Listen up and listen good. This is Joel 2, and it's all about God's mercy. God is gonna show mercy on His people, and send a great army to fight for them. He's gonna send a great fire to destroy their enemies. He's gonna send a great rain to bring forth a great harvest. And He's gonna fill the sky with a great wind to drive away the locusts that have been eating up the land. So get ready, because God is gonna do great things! That's the gist of Joel 2 - God is gonna show mercy and do great things. You got it?
