This week on Theology Simply Profound, Rob and Bob discuss Louis Berkhof’s little book, Summary of Christian Doctrine. We come to the third section of this book entitled, “The Doctrine of Man in Relation to God.” Chapter 12 of this third section brings us to a discussion of “Man in the State of Sin,” including topics like the origin of sin, the nature of sin, and the connection between Adam’s and that of his natural descendants.
