That’s the title of a series of lectures presented by Dr. Kim Riddlebarger of Christ Reformed Church in Anaheim, CA. I was introduced to one of the lectures via a Christian blogger (I can’t remember which one at the moment) and am listening to the entire series, the theme of which is the Reformed understanding of the Two Kingdoms (The Kingdom of God and the civil kingdom). It’s a great series so far and explains how we as believers are to live as members of God’s Kingdom and the civil kingdom at the same time. Go to http://christreformedinfo.org/mp3s-and-real-audio-of-academy/, which contains Dr. Riddlebarger’s lectures. You will see the series title (In the Land of Nod) and be able to listen to/download the sermons with the links provided.
