The world, dull of understanding, has even yet not really grasped the mighty principle upon which [George Müller] acted, but is inclined to think of him merely as a nice old gentleman who loved children, a sort of glorified guardian of the poor, who with the passing of the years may safely be spoken of, in the language of newspaper headlines, as a "prophet of philanthropy." To describe him thus, however, is to degrade his memory, is to miss the high spiritual aim and the wonderful spiritual lesson of his life. It is because the carnal mind is incapable of apprehending spiritual truth that the world regards the orphan Houses only with the languid interest of mere humanitarianism, and remains oblivious of their extraordinary witness to the faithfulness of God.
-William Henry Harding (Authored a number of books on revivalists including Brownlow North, Charles Finney, William Burns and Robert Murray M'Cheyne).
