From time to time here at Monergism we plan on taking some good theological resources and making them available in a way that they can easily be read in a smart-phone friendly format. Of course these can also be read on your laptop or tablet, but many of these were previously only available in such a way that smart-phone users could only see them in tiny almost unreadable text.
The following are a few that I have been working recently on that I thought you would find helpful and edifying.
