What hath the devil, or his agents, gotten by putting our great gospel minister Bunyan in prison? For in prison he wrote many excellent books, that have published to the world his great grace, and great truth, and great judgment, and great ingenuity; and to instance in one, the "Pilgrim's Progress," he hath suited to the life of a traveller so exactly and pleasantly, and to the life of a Christian, that this very book, besides the rest, hath done the superstitious sort of men more good than if he had been let alone at his meeting at Bedford, to preach the gospel to his own auditory.
John Bunyan
