If you don't know who the Puritans were then read on:
You may find this hard to believe, but there was a time when Britain used to produce excellent Christian books, that time was the 16th to 17th century, and the authors were called the Puritans.
These men were saturated in scripture, loved God, and devoted their lives to Him. Their books demonstrate their high view of scripture, and their devotion to God.
