Obadiah is the shortest book in the Old Testament and is considered among the minor prophets of scripture. The primary focus of this letter is to warn of God's coming judgment on the city of Edom. The city of Edom was arrogant and prideful before God and endures judgment from God. These similar attitudes can still creep up in the lives of Christians today, and have similarly damaging affects on our relationship with God. God's ultimately judgment towards people's sin has been taken care through the redemptive work of Jesus Christ.
