"Bunyan, although unlearned as to the arts and sciences of this world, was deeply versed in the mysteries of godliness, and the glories of the world to come. He was a most truthful, ingenious, persuasive, and invaluable writer upon the essentials of human happiness. To refuse his Scriptural instruction, because he was not versed in chemistry, mathematics, Greek, or Latin, would be to proclaim ourselves void of understanding."
