Rob Frost challenges Christians to be "salt and light" over ten issues in which they should be engaged - environment, poverty, multi-cultural society, a sex-mad society, the media, a politically correct age, genetics, the unborn, death and Society, including politics, health and defence. Accompanying each of the chapters is a TV programme from the God Channel, which can be downloaded free of charge. While informed by experts in each issue, the real appeal are Rob Frost's personal thoughts and experiences. In an increasingly secular world, should the Christian Church be taking a more obvious stance on world concerns?
