Logos’ free book of the month for February is The Works of Benjamin B. Warfield, Vol. 1: Revelation and Inspiration. Go here for more information.
I can’t tell you how excited I am to have this resource for Logos 4. I hold in my hand a copy of Warfield’s The Inspiration and Authority of the Bible, which contains many, yet not all, of the chapters in the volume on offer from Logos. Aside from having additional content from Warfield, I’ll be able to search and copy much easier with the digital book than with the hard copy. That’s the one plus about ebooks.
