Said Spurgeon of this book: And then how many souls may be converted by what some men are privileged to write and print. There is “Dr. Doddridge’s Rise and Progress of Religion.” Though I decidedly object to some things in it, I could wish that everybody read that book, so many have been the conversions it has produced.
Pilgrim’s Progress–a free online e-book. Spurgeon occasionally mentions the characters of this book in his devotionals
The Celestial Railroad-though not quoted by Spurgeon this is a wonderful add-on read to Pilgrim’s Progress and makes an analogy to our modern “Christianity”
