But he also wants anyone who enters this road to know what joys and obstacles lie ahead around the many bends. His book is by turns intensely practical and deeply devotional. Ever since Darwin, many Christians have been uncomfortable around science. Many of us have the feeling that science is trying to do away with the need for God. In the first pages of the book, Hearn, a life-long chemist and editor, separates what science can and cannot do.
Science can in no way establish the claim that nothing supernatural or eternal is real.
While this is not the book's emphasis, Hearn is very clear about what the limits of science are, and as Christians we must think clearly about what science can and cannot do. Using Being a Christian in Science as a basis, we will look at what scientists really do, why Christians might spend their lives in science, and what resources there are for believers who make science their chosen career. My hope is that you will see, not only the value of science, but, if you are a Christian young person who already loves science, you will see that this is a vocation to which God may be calling you. Science is changing the shape of our world and we need Christian scientists just as much as we need Christian teachers, or carpenters, or missionaries. Many Christians are not too sure what scientists do, and fairly sure they don't want to know.
