The book of Habakkuk is a different prophetic book because it relates a conversation between the prophet and God. Habakkuk questions God about injustice and God’s answers cover topics such as sovereignty and faithfulness. The book was written shortly before the Babylonian invasion of Judah in the 7th century BC.
Habakkuk’s initial complaint is about all the uncontrolled injustice and violence in Judah. “How long O Lord must I cry for help… with violence… but you do not help… why do you tolerate wrong?… the law is paralyzed and justice never prevails”.
God responds saying that he is at work preparing the Babylonians to administer justice to Judah. “They are a feared and dreaded people… their horses are swifter than leopards… they fly like a vulture… they deride kings… they laugh at fortified cities”.
Habakkuk is flabbergasted by God putting justice into the hands of the Babylonians. “O Lord, you have appointed them to execute judgement! O Rock, you have ordained them to punish!… why do you tolerate the treacherous? Why are you silent while the wicked swallow up those more righteous than themselves?”
