The Book of Habakkuk is one of the books in the Old Testament of the Bible. It is a relatively short book consisting of three chapters, and it primarily deals with the prophet Habakkuk's dialogue with God about the problem of evil and the apparent delay of divine justice.
Habakkuk raises questions about why there is injustice and violence in the world and why God seems inactive in the face of these issues. God responds by explaining His plan and the eventual punishment of the wicked. The book also contains a famous verse often quoted in religious and philosophical discussions: "The righteous will live by faith," emphasizing the importance of trust and faith in God's ultimate justice and sovereignty.
