For those of you who are interested you can go to http://www.logos.com/NationalBibleWeek#rules and submit and essay on Bible study to receive a $30 unlock credit for Logos Bible Software. That is at least one free book and you could have your essay published. If you are interested in purchasing Logos Bible Software, you can order one of the library packages from their site or download the Libronix Digital Library System for free and purchase books individually to build your own custom library. I highly recommend Logos Bible Software for everyone whether a pastor or layperson.
