The book of Habakkuk offers hope to people living in an evil world. It recognizes how dark and chaotic the world is and invites us to trust that God will one day deal with evil because He loves us.
Throughout the book of Habakkuk, we see that Babylon is an example of any nation that exalts itself above God and practices injustice, violence and idolatry. In the end, God reminds Habakkuk and every generation that God will deal with evil. We can continue to love and trust His timing and plan as we remain faithful to Him.
