The book of Habakkuk is Narrative History and displays Prophetic Oracle. Habakkuk wrote it approximately 612-589 B.C. just before the fall of Judah in the Southern Kingdom. Key personalities are Habakkuk and the Babylonians. As is true of the many other prophets, Habakkuk is a short book. The information in it was vital since it carried God’s message to His people. Its purpose was that Habakkuk was announcing a familiar message of judgment. He was identifying the wickedness and sin of Judah before them. Habakkuk declared that God is the "Rock" (1:2) and that they would be judged.
