God continues to confront his people's sins through the prophet Malachi. The people of Israel have been unfaithful to the covenant they have made with the Lord by refusing to offer acceptable tithes and offerings. They have robbed God by failing to be faithful in their worship of God through tithing. God calls the people to repent and return to him, demonstrating their faith through making appropriate tithes and sacrifices. If they do, the Lord promises to show himself faithful to them and provide for them.
