“This book is a treasure trove of information and theological thought; in addition, it is probably the best single-volume textbook on theology of any theological tradition. I myself draw heavily on Berkhof’s research on the immutability of God and the personality of the Holy Spirit.” Wayne Grudem “Berkhof can be our friend and mentor. He helped many of his contemporaries not to fall into heresy, igniting the hearts of people and tearing them out of the everyday life of Christian life.” Jeff Thomas "Berkhof's Systematic Theology has been a classic textbook in many Reformed seminaries for many years." Robert Raymond "This book remains the best introduction to Reformed theology ever written in the English language." Richard Müller “If we define theology as systematized knowledge about God, from whom everything comes, by whom everything stands, and towards whom everything is directed, then we must begin precisely with the doctrine of God. Not only should we not be surprised that dogmatics begins with the study of God, but, on the contrary, we should expect that all branches of systematic theology will be devoted in one way or another to the study of God. After all, theology as a whole is conceived as a doctrine about God, only in its first part is God the direct subject of study, and in the rest He is studied indirectly.” Louis Berkhof, from the chapter “The Existence of God”
