Theology is the knowledge of God, and since everyone is called to know God, everyone is called to do theology
(John 17:3). In fact, all of us start to do theology once we begin thinking about God. We are all theologians; the only question is whether we will be good theologians or poor theologians. This introduction to systematic theology by Dr. R.C. Sproul equips readers to be good theologians who are faithful to the Bible’s teaching about God and His ways.
