Why God is not an Idolater
Is not the essence of righteousness to place supreme value on what is supremely valuable, with all the just actions that follow? And isn’t the opposite of righteousness to set our highest affections on things of little or no worth, with all the unjust actions that follow? Thus the righteousness of God is the infinite zeal and joy and pleasure that he has in what is supremely valuable, namely, his own perfection and worth. And if he were ever to act contrary to this eternal passion for his own perfections he would be unrighteous, he would be an idolater.
-John Piper: The Pleasures of God
