A biology professor at a Christian university, Wilcox is committed to a strong biblical faith and to faithful, responsible science. He maintains that there can be no conflict between Scripture and the natural world because God is the author of both. The contentious debate over evolution is a result of a failure to recognize and respect the boundaries of science and also the boundaries of theology. The author addresses such topics as the age of the earth and the origins of life, including human life, exploring from a scientist's perspective what we know and how we know it. His objective is to help readers reach a point in their faith where they don't have to choose between God and science, but where they can embrace science as a part of the divine plan.
