Joel's arresting imagery – blasting trumpet, darkened sun and marching hosts – has shaped the church's eschatological vision of a day of wrath. Amos's ringing indictments – callous oppression, heartless worship and self-seeking gain – have periodically awakened the conscience of God's people. Two thousand five hundred years later, those prophetic words still speak powerfully. Tchavdar Hadjiev’s commentary on the books of Joel and Amos examines their literary features, historical context, theology and ethics.
