John Bunyan was an English preacher, but today he's most famous for writing the seminal Pilgrim's Progress, one of history's most famous and popular allegorical works. Bunyan even has a festival in his honor within the Church of England. Christian Behavior isn't as well known as Pilgrim's Progress, but it's an important treatise that Bunyan wrote to instruct Christians how they can serve God. Written while Bunyan was imprisoned in 1663, the beginning of the work says its purpose is "Teaching husbands, wives, parents, children, masters, servants, etc., how to walk so as to please God."
