Wherever man may stand, whatever he may do, to whatever he may apply his hand, in agriculture, in commerce, and in industry, or his mind, in the world of art, and science, he is, in whatever it may be, constantly standing before the face of his God. He is employed in the service of his God, he has strictly to obey his God, and above all, he has to aim at the glory of his God.

—Abraham Kuyper
Calvinism, 89-90
