I guess the first book I read by John Bunyan was Pilgrims Progress, which I ordered and am going to read again... Not to recently I finished online Grace Abounding To The Chief Of Sinners... Which I also recommend... Well looking around I found another one, another allegory called The Holy War... Just starting to read that one... And if any are interested here it is... Brother Glen
