The theme of the Logos Free book of the Month for August 2019 is biblical theology. You can get Peter J. Gentry and Stephen J. Wellum, God’s Kingdom through God’s Covenants: A Concise Biblical Theology (Crossway, 2015) for free. This is a concise version of their Kingdom Through Covenant: A Biblical-Theological Understanding of the Covenants (Second edition; Crossway, 2018). Since the larger volume is just under a thousand pages, this concise edition does not mean small: the book is over 300 pages long. I agree with Thomas Schreiner’s assessment this book is “a third way, a via media, between covenant theology and dispensationalism” by suggesting neither theological systems is informed by biblical theology. Gentry is an Old Testament professor and Wellum is a professor of Christian theology; both teach at Southern Baptist Theological Seminary in Louisville, Kentucky.
For $1.99 you can add another mammoth book from a SBTS professor on biblical theology, James Hamilton’s God’s Glory in Salvation through Judgment: A Biblical Theology (Crossway. 2010). Hamilton contributed a short primer, What Is Biblical Theology? and With the Clouds of Heaven: The Book of Daniel in Biblical Theology (NSBT 32; IVP Academic, 2014). For $2.99, you can add Gerald Bray, God Is Love: A Biblical and Systematic Theology (Crossway 2012). Christopher W. Morgan of California Baptist University says “God Is Love is a warm, conversational, and contemporary systematic theology written by one of evangelicalism’s leading thinkers. But it is much more. It is biblically saturated, historically rooted theological wisdom for the people of God.”
So for about $5 you can add almost two thousand pages of biblical and systematic theology to your Logos Library.
Logos Bible Software 8 is a significant upgrade to this powerful Bible study system. I did a “first look” review of Logos 8 here. The software runs much more efficiently than the previous version, that alone is worth the upgrade. Everything seems to run faster than Logos 7 and the upgrade is well worth considering. As always, there are less expensive paths to upgrading that will keep you from mortgaging your home. At the very least, download the free Logos Basic or the $79 Logos 8 Fundamentals (currently on sale for 20%). With either minimal package you can download and use the free book every month and build your Logos library.
These three and almost free books of the month are only available through the end of August, so head to the Logos site and get them before the offer expires.
