Banner of Truth is offering a new line of resources, called "Pocket Puritans."
These are booklet size excerpts from the Puritans which address issues relevant to Christians today.
You can read Richard Baxter on Anger Management, Samuel Ward on Living Faith, John Flavel on Impure Lust, or Jonathan Edwards on Heaven.
Cumberland Valley Bible Book Service is offering these at only $3.60 each! That's a good price and might be a good way to introduce yourself or a friend to these great Christian writings from the past.
