As a Christian who has functioned at the interface of biomedical science and faith for the whole of his professional life, Gareth Jones is aware of the tensions and misunderstandings that frequently arise both inside and outside the church. In this book he argues that Christians should not underestimate the importance of scientific contributions to an understanding of God's world. He works this out by reference to his own experiences in approaching a number of contentious topics. These include the use of embryos in reproductive technology research; the place of vaccines in combatting viral pandemics like COVID-19; and understanding the gender debate. Other examples he uses are the treatment of a genetic condition like cystic fibrosis and the importance of using only donated bodies for teaching and research in anatomy. In working at these borderlands, he recognizes that the best of biomedical science brings glory to God and enhances human existence. All these areas are transformed by applying Christian values, such as the dignity and equality of human beings. Over the years he has learned how to be comfortable working in these borderlands, even as they raise questions that trouble many within both society and the churches.
