His approach is deeply rooted within the Christian tradition and specifically designed for people who want to allow Scripture to shape the way they think and act. Gill's arguments are not drawn from ethical theory, though they are informed by it, but from the Bible, from Paul's admonitions to faith, hope and love, and from Jesus' Beatitudes.

Here is rich, biblical teaching that will help people from every walk of life, whether engineers, bus drivers, managers, restaurant workers, PTA members, parents, neighborhood volunteers, nurses, teachers, coaches, attorneys, journalists or physicians, fulfill their calling to be salt and light within their own spheres of influence.
