The theme of Amos’ message was that Israel had rejected the one true God in order to worship false gods. He also condemned the wealthy class of the nation for cheating the poor through oppressive taxes (Amos 5:11) and the use of false weights and measures (Amos 8:5). He urged the people to turn from their sinful ways, to acknowledge God as their Maker and Redeemer, and to restore justice and righteousness in their dealings with others.
