The small book of Zephaniah is Narrative History and Prophetic Oracle. Zephaniah wrote it circa 630 B.C. very soon before the fall of Judah in the Southern Kingdom. The purpose of this book was to show that God raised up his prophet Zephaniah to proclaim a warning of coming judgment and to encourage repentance.
The Southern Kingdom was complacent in their wicked lives. They not only suffered under wicked kings they also would suffer under the holy judgment of God. Zephaniah was God's method in bringing a stern warning of the day of the Lord €Near is the great day of the Lord...a day of wrath is that day€ (1:14-15). He also brought a message of hope, when the nation would be restored.
