John Piper has made many of his books available for free online in PDF format!

Here’s the link.

Some of Piper’s books are very deep and academic while others are much lighter. Many thanks to Piper and Desiring God Ministries for making these helpful books available for free. They even encourage you to print out the books and give them to other people…here’s their permissions statement:

You are permitted and encouraged to reproduce and distribute this material in any format provided that you do not alter the wording in any way, you do not charge a fee beyond the cost of reproduction, and you do not make more than 1,000 physical copies.

Enjoy!
