[Isaiah] preached to the masses only in the sense that he preached publicly. Anyone who liked might listen; anyone who liked might pass by. He knew that the Remnant would listen; and knowing also that nothing was to be expected of the masses under any circumstances, he made no specific appeal to them, did not accommodate his message to their measure in any way, and did not care two straws whether they heeded it or not. As a modern publisher might put it, he was not worrying about circulation or about advertising. Hence, with all such obsessions quite out of the way, he was in a position to do his level best, without fear or favor, and answerable only to his august Boss.
