Next to Obadiah, Haggai is the shortest book in the Old Testament. It has one specific purpose: to call the people of Judah to complete the rebuilding of the temple. Haggai reminds the people of the consequences of disobedience and obedience. He shows them that when they give priority to God and his temple, they are blessed and not cursed. When they are obedient, they receive the encouragement and strength of the Spirit of God.
Haggai also tells the people about the coming of the Messiah. When he comes he will bring judgment on the nations, but he will come to Israel and fill the temple with his glory.
Because of Haggai's encouragement, and the leadership of fellow prophet Zechariah and governor Zerubbabel, the temple was successfully completed in Jerusalem.
