From God’s Moral Government of Love:

“Why must God show that he is a fair, just, and loving, and not an arbitrary ruler? Because he cares about the opinions and good will of the onlooking universe. He is willing to have His government, His laws, which reflect His character, examined and evaluated by His created beings. This understanding of God’s sovereignty and justice in relation to human free will was the key that unlocked the door to the moral government of God; this conception of God’s government provided the framework for evangelical Christians insisting that human governments must act with morality and even love towards its citizens.
