I read part of J.I. Packer's book called "The Quest for Godliness" today. It is a terrific book about the English Puritans (who lived generally between 1550 and 1700). As I was reading I learned that one of the most notable Puritan theologians, named John Owen, died on this date in 1683...325 years ago.
Owen is, according to Packer "the hero of this book" and "was one of the greatest of English theologians." Referring to himself as a "teacher" Owen spoke and wrote at length about the importance of the cross and the Spirit in the lives of Christians in dealing with sin.
On sin, Owen wrote, "its nature and formal design is to oppose God; God as a lawgiver, God as holy, God as the author of the gospel, a way of salvation by grace and not by works, are the direct object of the law of sin."
Much of his work has been reprinted and can also be found online. Here's a link to The Puritan Library which contains is work online: http://www.puritanlibrary.com/
