In the shortest book in the Old Testament, we can learn big lessons. God spoke through Obadiah to condemn the nation of Edom because its people had rejoiced and gloated when Judah fell. The story of the enmity between Israel and Edom goes back to the twin brothers, Jacob and Esau. These brothers represent the difference between those who are spiritual, who seek God and obey His ways, and those only interested in the material world and their selfish desires.
