Once again the good folk at Logos are offering an excellent Free Book of the Month. This month Logos partners with P&R Publishing to offer John M. Frame, Salvation Belongs to the Lord: An Introduction to Systematic Theology (P&R, 2006) as a free addition to your Logos Library until the end of June. The book is a substantial 382 pages based on Frame’s lectures for the Institute of Theological Studies. William Edgar said this book “is at once vigorously orthodox and sweetly pastoral. We can be grateful for such a powerful and clear exposition of the whole range of theology.”

In addition to the Free Book of the Month, Logos is offering Brian Vickers, Justification by Grace through Faith: Finding Freedom from Legalism, Lawlessness, Pride, and Despair (P&R, 2013) for only $1.99. This book is part of the Explorations in Biblical Theology series (ed. by Robert Peterson). Tom Schreiner comments in his forward to the book, “sets justification in the context of the story line of the Bible. He doesn’t just give us an abstract and sterile explanation of the doctrine. We learn how justification fits with the biblical story and how it fits with our story.” Both of these books are great additions for people interested in the Reformed side of Christian theology.

As always, you can enter to win the rest of the Explorations in Biblical Theology series (11 vols., a 139.95 value) in the Logos library. Both of these books are excellent additions to your Logos library, so make sure to add them to your library before the end of the month.
