John Hasnas said this quote

“ People are more willing to support the exercise of authority over themselves when they believe it to be an objective, neutral feature of the natural world. This was the idea behind the concept of the divine right of kings. By making the king appear to be an integral part of God's plan for the world rather than an ordinary human being dominating his fellows by brute force, the public could be more easily persuaded to bow to his authority. However, when the doctrine of divine right became discredited, a replacement was needed to ensure that the public did not view political authority as merely the exercise of naked power. That replacement is the concept of the rule of law. ”
