A key concept in the book of Joel is the “day of the Lord”—a pivotal time in which God confronts evil in a dramatic way, bringing salvation to His people. In 1:13–2:17, Joel prophesies a coming “day of the Lord” that will bring a wave of locusts like a relentless army and beseeches God’s people to repent. In response to their repentance, God promises to heal and restore the land (2:18–27). The concluding portions of the book point to a more distant and even greater “day of the Lord” (v. 31). In that day, God’s presence dwells among His people in a way that’s accessible to all (v. 32), and His healing presence will renew all creation.
