Wayne Grudem is one of the most influential evangelical theologians in the world today and has written much to help the church think biblically and live faithful lives that honor Christ. As a co-editor and contributor to Theistic Evolution: A Scientific, Philosophical, and Theological Critique (2017), he presents many excellent biblical and theological criticisms of theistic evolution. However, in this careful analysis of his two chapters, I will demonstrate that most of his reasons for rejecting theistic evolution are also reasons that he should reject all old-earth creationist views, including the view of John Lennox that he now favors. In his acceptance of millions of years of geological and cosmological evolution, Grudem is making the same biblical and theological errors that theistic evolutionists make. To be biblically consistent, he must abandon his compromised old-earth position. The character of God, the truth and authority of Scripture, and the gospel itself are at stake.
