John Piper Sermon Manuscript Library for Libronix / Logos Bible SoftwareEven though every sermon manuscript in the John Piper Sermon Manuscript Library is available for free from DesiringGod.org , the Manuscript Library is worth the cost:
1. Available where there is no internet connection.
2. Searchable: The powerful search features of Logos will help you find appropriate sermons and excerpts from sermons quickly. I have discovered numerous gems that God has used to affect me relating to a certain passage or topic since I have owned this software that I would never have been aware were even available before.
3. Key-linked: Piper makes extensive reference to Bible verses throughout his sermon manuscripts, and often I have been guilty of not looking up the verses simply because it was too much work. Now, I can just hover my mouse over the references and the verse pops up.
4. Seamless integration with the way I study: My study of the Bible occurs almost exclusively now with Libronix (Logos Bible Software). I have searchable and quick access to all my study notes, multiple versions including original languages, commentaries, and thousands of books. I have found that if I have a resource and it isn't in Libronix it just isn't accessed because of the added work of checking that resource.
For these reasons, I highly recommend The John Piper Sermon Manuscript Library. If you don't own Libronix already, the best way to start is with one of the collections
