In this book, we will explore the mystery of God; that is, the doctrine of the Trinity or Triune God. For years, the debate continues as to whether Jesus Christ and the Father are the same or if they are separate. Answers to this controversy are within the word of God which clearly reveals the truth. In addition, we will plainly discuss the Godhead; that is, the divine nature of God. Through the presentation of biblical truth, we will bring clarity to this controversial subject.
