Why is the justice of God important for rulers?

In 2 Samuel 23, David speaks of the necessity for rulers to be just and to rule in the fear of God. This reflects the holiness and justice of God Himself, whose governance is characterized by righteousness. Rulers are accountable to God's standards and must be aware that they will answer for how they lead. By ruling justly, they create an environment reflecting God's kingdom and facilitate peace and order among the people. It is a reminder that while God appoints rulers, they must always remember their authority comes from Him and act accordingly, seeking His wisdom and guidance in their decisions.
