Read it any years ago mostly all I remember about it was thinking it was a rip off of Pilgrim's Progress
I've heard many times since then that there are serious doctrinal problems with the book but I don't remember what they are and I wasn't a Christian when I read it so I wouldn't have recognized the anyway
This book has been a blessing to many but sadly Hannah embraced 'Universalism' later in life and new age teaching so be careful with later books by Hannah Hurnard. 'Hinds Feet on Higher Places' was accepted by mainstream Christians as a classic.
