“A graceless pastor is a blind man elected to a professorship of optics, philosophizing upon light and vision, discoursing upon … the nice shades and delicate blendings of the prismatic colours, while he himself is absolutely in the dark! He is a dumb man elevated to the chair of music; a deaf man fluent upon symphonies and harmonies! He is a mole professing to educate eaglets.”
Charles Spurgeon
