"His words had power because they accorded with his thoughts; and his thoughts had reality and depth because they harmonized with the life he had always lived. It was not mere breath that this preacher uttered; they were the words of life, because a life of good deeds and holy love was melted into them. Pearls, pure and rich, had been dissolved into the precious draught."
